using mass data. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. b) If two samples of different elements have the same mass, they contain the same number of moles. The basic equation = mass of element / mass of compound X 100% For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be: 1M Next question 393 views was this helpful I find the atomic mass of chlorine in potassium?!
