Please include all the calculations. A compound is found to be 30.45% N and 69.55 % O by mass.  If 1.63 g of this compound occupy 778 mL at 0.00°C and 775 mm Hg, what is the molecular formula of the compound? Determine empirical formula of the compound using its percent composition given.  To determine molecular formula, you need to calculate molar mass of the compound using ideal gas law. With given volume, temperature and pressure, you can calculate number of moles, and you have mass in grams of this number of moles. Remember that molar mass is mass of 1 mole of substance.
