The molar mass is 62 g/ mole & the empirical formula is CH3O. Use each element's molar mass to convert the grams of each element to moles. .328g is hydrogen, so you shouldn't divide by 16g. A 2.402-g sample of made of C, H, N and O contains 1.121 g of N, 0.161 g H, 0.480 g C, and an unspecified amount of oxygen. The mass of the empirical formula above is 44.0 g/mol, so the empirical and molecular formulas are the same. So you calculate the Empirical formula as above, then determine the weight of one mole, divide that into the molar mass, and that tells you how many times it is bigger, and then multiple the emprical formula by that number. Both have the same empirical formula, yet they are different compounds with different molecular formulas. Doing the calculation for the H, it is 0.33068 grams of H another HUGE mistake you made (0.3307 g of H is 0.3281 moles of H, which is, I suppose where you screwed up). Q.
