CxHyNz is the empirical formula of an organic compound. When 0.3 g of the given compound is completely burnt in excess of oxygen, it produced 0.792 g of CO2 and 0.378 g of H2O. In Dumas' method for the estimation of nitrogen, 0.3 g of the same organic compound gave 33.6 mL of nitrogen gas at 300 K temperature and at 576 mm of Hg pressure, then the value of X×Y×Z is. ( Aqueous tension at 300 K is 15 mm of Hg, use R= 0.08 atm-L/mol K)
