Dimethylhydrazine is a carbon–hydrogen–nitrogen compound used in rocket fuels. When burned in an excess of oxygen, a 0.312 g sample yields 0.458 g CO2 and 0.374 g H2O. The nitrogen content of a 0.486 g sample is converted to 0.226 g N2. Its molecular mass is found to be 120 u. For dimethylhydrazine, determine its (C: 12.01 u; H: 1.01 u; N: 14.01 u; O: 16.0 u) (a) mass percent composition; (b) empirical formula; (c) molecular formula.
