FROM COMBUSTION DATA 1. A combustion of 0.202 g of an organic sample that contains carbon, hydrogen and oxygen produce 0.361 g carbon dioxide and 0.147 g water. If the relative molecular mass of the sample is 148, what is the molecular formula of the sample?

2. A 1.367 g sample of a substance was burned in air to produce 3.002 g CO2 and 1.640 g of water. If the sample contains only C, H and O, determine the empirical formula.​
