Given the molecular formula, you would find the molar mass, the sum of all the atomic masses. You would then divide the weight that you are given by the molar mass to find out how many moles of that certain compound you have.
Given the molecular formula, find the atomic weights listed under the element in the periodic table. Multiply the element's weight by the appropriate subscript and then add all the weights together. This will give you the molecular weight of a mole of the molecule, and thus its molar mass. You then divide the given amount of molecule by this newly found molar mass to find the number of moles in the compound.
