Hydrazine, ammonia and hydrogen azide all contain only nitrogen and hydrogen. The mass of hydrogen that combines with 1.00 g of nitrogen for each compound is 1.44*10-1 g, 2.16*10-1 g and 2.40*10-2 g, respectively. Using the law of multiple proportions, what could the empirical formulas of these three compounds be?
