holy this is light years easier than how my science teacher taught me!! she taught us something similar but instead of straight dividing we had to do this weird cross multiplying thing that i never got the hang of. super helpful video! finally helped me understand!

helped 5 hrs before exam

thanks man for the brief explanation it was impressively helpful

Very well made, thank you.

Hi, if i have a Molar mass of 314.45 g/mol and wish to make up 2.0 uM of solution into mls, what would be the answer please mate? I have tried for 2 hrs to solve this. You make it easy where others include lots of confusing unhelpful steps.

great video

Thank you.

Thank you for this video. However, I have a question. What if we only have molar mass? Let me explain the problem. Olympic cyclists fill their tires with helium to make them lighter. Assume that the volume of the tire is 860 mL, that it is filled to a total pressure of 125 psi, and that the temperature is 24 degrees Celsius. Also, assume an average molar mass for air of 28.8 g/mol. Part A. Calculate the mass of air in an air-filled tire. M1. Part B. Calculate the mass of helium in a helium-filled tire. M2. Part C. What is the mass difference between the two? Thanks!

any luck on solving this?

X(any number) * moles = x* Molar mass

Understood thanks🎉

video saved me from failing my chemisty test

Thank you so muchh

you put 70.0 from where??

its a example

👏👏👏👏👏

Just took the quiz, had no idea they were different things 🌚

Can you make a video for converting miles to grams? ;-;

Do you mean Moles to Grams ? Got one for that !

what if theyve only given the molar mass?

Impossible. They have to tell you HOW MUCH of the substance is there.

@@chemistNATE either my textbook is weird or I’m not seeing something. Could there be a way to do it with molar mass and molar ratio?
