Hi the following comes from my first homework assignment in AP Chemistry. I am totally lost on this question and don't know where to start. Thanks a lot in advance!!!!!

A 0.1247 g sample of ascorbic acid, Vitamin C, was burned in a carbon-hydrogen combustion apparatus to produce 0.1869 g of carbon dioxide, and 0.0510 g of water. Ascorbic acid contains only carbon, hydrogen, and oxygen. Determine the masses of C,H, and O in the sample and then determine the simplest formula.
