molar mass

Postby 905092269 » Sun Oct 07, 2018 11:23 pm

How would I find the molar mass of a sample if a single molecule of it weighs 5.34 x 10^3 g?

You would have to use stoichometry with avagadros number and then molar mass.

Given the g within one molecule, you must multiply this by avogadros constant, 6.022 x 10^22 mol^-1. This comes from the idea that in order to find the mass of one molecule of anything, you take the molar mass of the substance from its composition, and then divide it by Avogadro's number to find the amount of grams per molecule. In order to solve for a question like you are asking, it is best to rearrange this staple relationship between molar mass, avogadros number, and molecular formula.
