Calculate the relative density of NH3 gas as H2 gas.

The relative density of one gas in another is found by the formula: D = M1 / M2, where M1 is the molar mass of one gas, M2 is the molar mass of another gas. Let us determine the molar masses of gases according to the periodic table: M (NH3) = 14 + 3 * 1 = 17 g / mol; M (H2) = 1 * 2 = 2 g / mol. Find the density: D = 17/2 = 8.5. This means that ammonia is 8.5 times heavier than hydrogen.
Answer: The relative density is 8.5.
