The beta-blocker drug , timolol, is expected to reduce the need for heart bypass surgery. Its composition by mass is 49.4% C, 7.64% H, 17.7% N, 15.2% O, and 10.1% S. The mass of .0100mol of timolol is 3.16 g. (a) What is the simplest formula of timolol?
So... answer should be C13H24N4O3S. But I keep getting 13.20C/S and 24.25H/S, which means that I need to multiply them by 5 and 4 so that they can be a whole number.... and I don't think that works... so.. help

oh and what would be the molecular formula of this (timolol)?... would it be the same since 3.16g is less than the molecular weight?
