Molar volume and molar mass - Need help with 2 Questions (1 Viewer)

[erika5d]

Hi guys!


Our teacher gave us this worksheet today regarding molar volume and molar mass. I'm fine with the rest, but I have totally no idea how to these two questions...



Any help will be greatly appreciated!


p.s. In my textbook and the syllables, I couldn't find any information about this whole molar volume stuff, is it not in the Preliminary course?

the equation you need is n = volume / molar volume
you need to get n from the mass and put it into the above eqn
im pretty sure its in the prelim course
