I love 😘 physics because he had become for me upper wallah 😁during exams
@@radhapriyadasi_72 exactly 😂
@@dimensionsless0212 😅🤣🤣
class notes nahi mil skta kya??
@@user-vh5gi5ov9x Bro kya tumhe class notes mile ?
Agr mile toh btana
HARDEST PART IS NOT THE QUESTIONS BUT THE STUPIDLY LENGTHY CALCULATIONS.
I agree lol
Lekin competition idhar hi kam hojata hai
Jo alas nhi karega wo aage chala jayega
bro these mf units bro

@spicy1pastryya kya hota hay
@@Andromedatheclosest 🤣
For question 2 you can find molality by by the no of moles of agno3 because it is acting as solute
1Molar =1 mole in 1000mL
1/1000mole=1mL
1/50 mole = 20 mL
Moles of Agno3 is 0.02
Now mass of KCl is 25 g
Now you can find molality
👉No.of moles of Agno3/mass of KCl (in kg )
Which is 4/5
And after multiply
i×kf×molality
2×2×4/5=3.2( near to 3)

12:18
20:43 convert pascal into bar
23:21 weight by weight percent question
29:53 non volatile solute means i(vant hoff factor) = 1 as alpha will be zero
33:15 if not given take dissociation or association 100 percent means alpha =1 therefore i=n n = 2 in case of agbr
42:51 taking ethanol as solvent as freezing point depression constant is always defined for solvent
44:59 i=1 as ethanol is non polar solvent
46:03 henry law question
50:19 both liquid and gaseous phase question
56:13 no info given about i so take i = 1
Padhle bhai... ye sab karne se ghar nahi chalega

Thank you Sir for this session..!!🙌❤
Thank you very much sir for such an amazing practice session ❤
One of the best teacher in physics wallah
कौन कौन मानता है कि राहुल सर एक महान शिक्षक है।🙏🙏🙏🙏🙏🙏
इसमें कदापि शंका नहीं मित्र
भ्राता हम मानते है
सभी शिक्षक महान ही होते है ❤❤
@@monishbondre अति उत्तम वचन भ्राता!
शिक्षक तो भगवान का रूप होते हैं उन में से एक हमारे राहुल सर है इन्हे शत शत नमन
One of the best techer of physical chemistry 🎉❤❤
Bhai aapne jee main ka attempt diya?
Agr diya to aapko in videos se Kitna help hua
Please btado brother
Best explanation thank sir ❤❤❤❤❤
i think u are going to be the next famous teacher on yt
Most Underrated teacher ever ✅
💯 WORTH WATCHING

Agar solute ka volume large hota aqueous solution se to hum.
Solvent ka weight find krne ke liye acetic acid ka density rakhate kya?
Very very❤ Thank you ❤ sir 2ghante lagatar question krwane ke liye
Literally pure lecture me apki aur humari energy jra bhi down nahi hue kyuki sab question ho rahe the ❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Love you from ❤
Being an NDA aspirant, I answered 80% questions correctly!! All thanks to Alakh Pandey sir for his indomitable 5-year-old superb lectures ...
Ye teacher to mast hai 🗿❤️🗿
Excellent teaching 👌🏻👍🏻👌🏻👍🏻👌🏻👍🏻👌🏻👍🏻👌🏻👍🏻👌🏻👍🏻👌🏻👍🏻👍🏻👍🏻❤❤❤❤... Very nice explanation and simple methods to solve enjoyed it😊
Sir mein yes no bolta hoon par aapko pata kaise chalega 😁😁😁😁😁❤️❤️❤️
sir heart'beat se pta kr lengee😅😅

Main sir ko call krke bata dunga
Main sir ko call krke bata dunga
1 bar== 1atm or 1atm= 1.01325 bar
1 atm= 1.013*10^5 Pa
Percentage of dissociation/100 = alpha
In freezing point formula , molality of solute mein nich solvent's mass not solute jiska ∆Tf nikal rhe
1atm=10^5 Pa
i for glucose sucrose alcohol urea =1
X = moles in liq phase
Y= moles in vapour phase
summary points of solution
11:28 equation
45:50 solvent ka hi depresion const define hota ha isliye ethanol solvent ha = mass of solvent is 50 not 48.2
1:16:08 calculation redooo
1:26:00 pa ma pucha ha to bar ko 10^5 sa multiply krna ha
1:35:25 approximations
1:38:15 dekho ques ky pucha ha
redo the above ques and try hw ques
best of luck for 2 nd attemt
57:05 actual temp is in Kelvin according to all units given , so it is misprint in question
Change in temp. is always same in both the units ...ye confuse karne ke liye celcius m diya h...change Kelvin and celcius m same hi hota h ..to vo thik h..
I hope you got it👍🙂
@@prachigaur8182 okay 👍 thanks
Na 1D Na 2D aur na hi 3D only Rahul Dudi
Great teacher ❤
You are a great sir❤❤❤
Thank you Sir❤
What a positive vibe
bookmarks :
27:37 - retry (calculation intensive and bit confused )
32:21 - rety (conceptual doubt - rxn nahi ata )
lo reply karke yaad dila deta, revise karlo
@@abhinav7352 arre thank you so much almost bhul gaya tha yeh revise karna
firse padhle bhai
Retry krle
17:15 re do
23:01 f• freezing point of pure solvent that is water 273.5 Kelvin
49:23 sir can't we use the formula for moles of water volume/22.7. ??? Instead of converting volume into gram and then dividing by its molar mass??
I think we can use this formula only when substance is in gas phase
@@anjanab.krishna2052 yep, exactly 💯
😊
@@anjanab.krishna2052 It is valid only for gas and at STP.
Thanks a lot sir!!😊

Best teacher of physical chemistry
Sir mene aap ke sath sare question kiya solution chapter mere fav chapter hogaya h sir thank you sir for this session ❤
literally sir love you very well strucutred way of solving question
on an average ek session me kitne q. karwate hai teachers?
almost saare question numerical me hi kyun diye nta ne .....jab answer itne bhayanak he toh😫
Bro Aaj kal most of the physical ke question integer mein hi aate Hain inorganic or organic ke MCQ mein aate Hain
Jee is also bhayankar exam
Amazing session 🤩
Completed🤓✅✅✅✅✅✅✅ thank you sir 💖💖💖💖💖
@@surendrabishnoi2929 lakshya wale hona
37:43 sir 3no me gadbad hoi hai.....! 😢😮
Sir at 1:12:52 apne 2.8 use kia hai instead of 2.5
Dudi sir ioc physical acha padhate hai aur Faisal sir organic. But inko opposite roles de rkhe h 😭
26:21 calculation is very critical
Ha baby ❤
03:00 If Density of Solvent 1 then molality = molarity
15:00 Moles of KCL = Moles of AgNO3
1:11:10 no of glycine units
1:37:00 Conversion
1:18:29
28:22 silly mistake that maine diff in T ki jagah sidha lagaya tha
Gajab josh ke sath class start hua sir thank you
45:42 sir, why is the ans 80, bcoz molar mass of ethanol is 62?
Thank u so much sirrr❤❤💙
Vapour pressure of pure liquid of A 114 hai Answer....
Sir aapki slide mai answer wrong hai
For my revision
18:11 kcl mai depression nikalna hai to law of equivalence laga ke molarity nikalna usse nikal jayega
25:16 iss question mai mass of solvent 100 nahi mass of solution 100 hai to usko minus karke solvent ka mass nikalana or phir molality mai solvent ka hi mass dalna
Bhaiya aapko in videos se kitni help mili
jee mains me aapse question solve hue in videos ki help se ya nhi
Plz btadijiye
@@smileboy1357 bhai mera nahi hua 91.3 aya jee mai video se to bahot help mili but agar aap koi app se pyq solve karoge to jyada Better rahega ( Maine marks se kiya tha )
@@RamHirani-lf9im thanks for guidance bhai
Kya batau sirji.. bas shukriya yaar❤
Sir maine aapki koi baat par vishwaas nhi kiya or sare question khud solve kiye😁😁😁😁
Nice
Bhut shi
Thanks sir ❤
Sir plzzz, theoretical and graphs based questions bhi rkha kijiye 🙏🏻🙏🏻....
Thanks for this very helpful video ❤❤❤
Anyone before test?
I am hare

MOLARITY = MOLALITY FOR LARGE CONC
Hello sir please reply me
I am your big big big fan of your teaching organic chemistry in yakeen 2.0
19:00 warra concept, moles of agno3=moles of kcl na hence molarity can be found out
26:00
51:00 important
1:09:00
please make one for ionic equilibrium too
0:00 to 42:00-2023 pyqs
Please increase frequency of videos 2nd attempt is near
Aapka result kya rha ??
1:09:09 mass of acetic acid will 1.2×1.02?
Thnx ..

Thank you Dudu sir
1:09:38 I thought something wrong in this Question . 🤨😶
At 1:05:53 why did we take 1.5 as vol of acetic acid instead of 1.2 ml??
Exactly
Notes kaha hai iske
Finally rahul dudi sir ka video mil hi gya solution ka
Sir if we practice these type of questions can we attend a question from solutions chap in jee mains ??
Ysss
No
firstly, vo main hota hai mains nhi 🤣...jisko bhi dekho mains mains krta rhta hai 😂
pata nhi but is lss ke que nhi hore the ab confidence aa gya hai
Love you sir❤❤❤😊
SIR ALMOST SARE QUESTIONS KHUD SE KR LIYE MAI IS BATCH KE PPT USE KR RHA HU PYQ KE LIYE KYU KE FINANCIAL PROB I CANT AFFORD TO PURCHASE A PYQ BOOK OF 2 TO 3K
41:40 yha par answer solve karne par 308 aa rha hai dudi sir
Suna suna hai ya suna suna hai ❤
1:09:46 at here weight of solute is Wrong as I think
Calculation toh hogi hi nhi exam me
Thanks ❤
You are best teacher ☺️💕
lakshyas are here✊👊👊🤛
thank you sir
My practice done for tomorrow test
7.00 Sir lakshay jee 2025 me rohit mahajan sir ne delta Tf ka formula Delta Tf=kf*m diya hai bus i ka koch nhi kaha hai
question 2 mARKED FOR REVISION
27:17
∆Tf ki value nikaalo
Khud se or calculator se match kro
Ek magic dikhega 😂
i was confused by this for 10 mins 😆😅
Mera answer 50231, calculator ka 30 🥰🕺🏻
No of queations??
1:10 mass of acetic acid 1.02×1.2 hona chahiye n 🤔
thank you sir for the classssssssssssssssss
Sir we are lucky aap jasa sir hama mela
At 18:20 why here molality and molarity are taken same??
Because density is 1g/ml😊
@@shivam-eh2ck ohk thanks🌸 to ye chiz hr jgh use kr skte h mtlb jha pe 'm' pta ho but 'M' nhi h or density agr 1g/mL-¹ hai to we can take m~M ???
