I love your vids, straight to the point, visually interesting and it helps me to understand it perfectly thank you so much you're saving my college career
Got a video showing how you can convert between the types of concentrations? Converting between Molarity, Molality, Percent by Mass, Percent by Volume? I just wanna look at a bottle of isopropyl alcohol and know its molar concentration.
Professor, why we don't have volume/mass percentage concentration term? Plz reply professor..i searched many books but they haven't addressed this doubt
A volume PER mass? Do you see how that makes no sence whatsoever? A solute has no volume of its own. It may impact the solvent's volume either way i.e. the solution can have greater or lower volume than the solvent on its own. Or measure the volume of a solid solvent before dissolving? There is a reason we never measure amounts of solids in terms of volume... it gives us extremely crappy information about the amount. Or you may be thinking in terms of liquid in liquid solution. But why measure volume against MASS in this case? Especially in miscible sölutions like alchohol in warter, volume per volume just makes sense.
What a coincidence! I have an exam on the same topics, like mass percent, molarity, molality, normality tomorrow.
Thanks professor Dave!

The way of explaining is simply awesome😍😍😍.love chemistry,😍love you professor dave
I tried to concentrate on the video, but I solute you.
Just. I am fall in love with the way he explains.
Go get 'em, Dave.
what a coincidence! thanks to you l passed my exam! thank you
U speak like u are afraid🤔 No expressions, just talking 😌 But I like the information

4:00 regarding 10%aq NaOH. I always prepare it by dissolving 10grams in 100cc H2O not as mentioned by dissolving 10grams in 90grams (90ml) of water
Thank you
TYSM! This is very helpful!
You are the best
Thank you jesus chemistry
Thanks,sir
good
Nice 😊
What's up professor?
NaOCl
hey your emil doesnt work
