The relative density of the gas in air is 1.52, determine the mass of 1 liter of this gas.

Let’s find the molar mass of the gas:

M (gas) = M (air) * Dair (gas) = 29 * 1.52 = 44 g / mol;

It is known that under normal conditions one mole of gas occupies a volume of 22.4 liters. From here we find the mass of one liter of gas:

m (gas) = M (gas) / VM = 44 / 22.4 = 1.96 g.

Answer: m (gas) = 1.96 g.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
