##### Molecular Formula of the Compound
« on: December 24, 2017, 06:27:57 AM »
A 1.420 g sample of gaseous compound occupies 215 mL at 31.2 °C and 836 mmHg. The compound consists of 42.6 % O , 48.0 % C  and 9.40 % H by mass. What is the molecular formula of the compound?

What have you tried? Can you calculate, for instance, the empirical formula from the percentage data? Or the molecular mass from the other data points?
