Find the molar mass of a gas with a density of 1.43 g / dm3.
| June 1, 2021 | education
The molar volume for any gas will be the same – 22.4 liters.
Let’s convert liters to cubic decimeters: 22.4 l = 22.4 dm3.
The density of a substance is the ratio of its mass to its volume.
Hence the molar mass of the target gas:
22.4 * 1.43 = 32.032.
This is the molar mass of oxygen.
