This video shows you how to calculate the molar mass for several compounds using their chemical formulas. You can see a listing of all my videos at my website, www.stepbystepscience.com
Im a Jamaican its my first time doing chemistry and i find it really hard but your videos are really good i am very greatful for them keep up the good work well appreciated
@eman fatima CaCl2 is 1Ca and 2Cl because the 2 is a subscript and comes after the Cl it only applies to the Cl. In order for it to be 2Ca and 2Cl the chemical formula would have to be Ca2CL2, both of the twos being subscripts. Does that help?
This video was insanely helpful!! Literally finished my homework in ten minutes after watching. I think it was the first time I actually understood chemistry!
Yes, I just try to go over everything Step-By-Step...in fact You can see a listing of all my videos at my website, www.stepbystepscience.com Thanks for the comment.
When you have time, can you explain the differences of all these calculations as to why we are jotting back and forth between them so much and in so many ways numerically? Why are we? How should we ? Is there even a more in-depth visual or is the idea so tiny to see that I cannot even imagine what we are trying to bounce back and forth trying to accomplish so many things? I don;t see what I need to with these yet, no a-ha or anything... I mean, I see little tiny moles and atoms... dots... and well I don't see how they are needing to be rearranged and why, and how they are being used and combined in so many different ways. I want to though! You are so smart and I feel like I am a micro particle that cannot make sense out of particles! I mean, you have explained this better than anyone else I have seen yet! Your a great teacher, I feel I can find some more clarity than I have yet with the way you are showing us how to organize this, I thank you for your effort and time :) . I just hope I can finally get it before my final !
@@jadenjones693 I can't believe you responded to my 3 year reply to a 5 year comment XD I hope you have fun and do well in chemistry, it's pretty fun but also hard. Have a good one :D
hi brian ,,, in my periodic table hydrogen atomic mass is 1,0 and sulfur 32,1 pls help me how did you write the molar mass in 2 decimal place ,,pls it' s urgent i have a che unit 6 exam tomorow
As you said molar mass is mass of 1 Mole of substance, sir can we find molar mass for 2 moles of any substance this is getting me confuse. BTW THANKS FOR THE VIDEO THIS IS SO HELPFUL 😭❤️
+akmal hakim The dot is not a multiplication sign it means the there a two water molecules "attached" to the CaCl2. That sense it is more of an addition sign. To get the molar mass add the mass of one CaCl2 and 2 H2Os. Does that help? You can see a listing of all my videos at my website, www.stepbystepscience.com
+Brian Swarthout yes.. it helped. thanks. actually in my add maths class... The dot means multiplication so I got confused.. thanks anyways. great video.. :)
I don’t even think you’ll see this comment but why is my periodic table different like I have different relative atomic mass than your periodic table for example you have Sulfur-32.07 and I have in my periodic table Sulfur- 32.01
Yes, the numbers can be a bit different depending on rounding and other factors. Use the numbers form the periodic table your teacher gave you...I read all my comments.
Not so useful .. what if we dont have a periodic table and we need to use the Ar .. find the amount of moles then the molar mass .. this is so simple , nothing useful ...
learned more from one youtube video then my chemistry teacher taught!
That is unfortunate, but I am glad that I was able to help out.
Im a Jamaican
its my first time doing chemistry and i find it really hard but your videos are really good
i am very greatful for them keep up the good work
well appreciated
same
This is the best molar mass calculation i have ever watched so far
Thanks so much!

I shared your videos with my 10th grader. She understand you better than she understands her teacher! Awesome!
Thank you very much for doing so and thanks for the positive comment it means a lot to me!
Excellent!!!!! Very helpful, the way our instructor explained to us was much much more difficult
straightforward and to the point with great examples. thanks
Thank you!!!!!!!! I wish I had you as my chemistry teacher. I actually get it now. My teacher goes SOO fast and we get so lost.
Melissa Ramirez Glad that the videos are helpful to you.
Thank you so much I didn't realise it was that easy
you are very welcome!
Great and clear. Thank you for your time
Amazing techniques to solve molar mass! Thank you so much for your help!
Thank you so much. Your explanation made this process a whole lot easier.

hi brian ,,, in my periodic table hydrogen atomic mass is 1,0 and sulfur 32,1 pls help me how did you write the molar mass in 2 decimal place ,,pls it' s urgent i have a che unit 6 exam tomorow
Only because the the rounding is different on different periodic tables.
Jeeeeesus this is so helpful 😭🤣
wow ...............cant you be my
physics teacher
:D I Actually Understand Now...Thanks (Y)
this helped me so much i have a test for chemistry and I need to pass!!
Hope the test goes well!
What application did you use to create this video? Thanks.
Matthew C A simple HD webcam, keynote and Screenflow to capture the on screen images and the video from the webcam.
Thanks!
Do you not have to account for significant figures?
Ben Swain For high school kids I try to not get to hung up on the details; aka significant figures.
As you said molar mass is mass of 1 Mole of substance, sir can we find molar mass for 2 moles of any substance this is getting me confuse. BTW THANKS FOR THE VIDEO THIS IS SO HELPFUL 😭❤️
Why didn't you use g/mol as the unit?
How do you get the
h 2 x 1.01 g
I get the h2 just not how it x 1.01g
Because there are 2 atoms of hydrogen.
thank you it has been very helpful
for the calcium chloride.... what does that black dot means? is it multiply
calcium chloride and water I mean
+akmal hakim The dot is not a multiplication sign it means the there a two water molecules "attached" to the CaCl2. That sense it is more of an addition sign. To get the molar mass add the mass of one CaCl2 and 2 H2Os. Does that help? You can see a listing of all my videos at my website, www.stepbystepscience.com
+Brian Swarthout yes.. it helped. thanks. actually in my add maths class... The dot means multiplication so I got confused.. thanks anyways. great video.. :)
How is the molar mass of a substance equivalent to the average atomic mass of that substance?
Julia Kim it is really two ways to say the samething
U R the baist meaning beast and best
Gee thanks!
thanks! mrs ball, if your reading thus, i think your a good teacher, but you might wanna take a leaf out of this guy's book
You said that the molar mass of lead is 207.02, but im pretty sure its 207.20
Sorry...
in my physics text book ..........carbon is 12.o and aluminum is 27.0 so whats the cause for different mass ?
+jade malan In your book it is just rounded to the nearest whole number
got many things through the video.
i wish if you were my teacher
Very nice of you to say, thanks. You can see a listing of all my videos at www.stepbystepscience.com
Am I the only one watching this 8 year later
Hopefully not, but thanks for watching.
I don’t even think you’ll see this comment but why is my periodic table different like I have different relative atomic mass than your periodic table for example you have Sulfur-32.07 and I have in my periodic table Sulfur- 32.01
Yes, the numbers can be a bit different depending on rounding and other factors. Use the numbers form the periodic table your teacher gave you...I read all my comments.
so why is a mole 6.02 x 10^23? I looked it up. The guy who invented the system was named Dumas. It's the Dumas method..... Nuff said.
Op
fuuuuuuuuuk chemistry. but thanks for this great vid bro,
just subscribed to you :)
