The relative density of the gas in terms of hydrogen is 15. Find the molar mass of the gas and the mass of 10 liters of it under normal conditions.
The hydrogen density D (H2) is the ratio of the molar mass of the gas to the molar mass of hydrogen (2 g / mol): M gas / M H2. If D (H2) = 15, then M gas = 30 g / mol (for example, nitric oxide NO).
The molar volume of any gas at normal conditions is equal to 22.4 liters, which means that 10 liters of our gas have a mass of (10 / 22.4) * 30 = 13.4 g.
