What is the ratio of the density of uranium hexafluoride UF6

What is the ratio of the density of uranium hexafluoride (UF6 - a gas) to that of air? The molar mass of uranium is 238 kg/kmol.

Solution

Solution :

Density of Uranium hexafluoride is 5.09 g/cm³

Density of air is 1 g/cm³

Hence ratio= Density of Uranium hexafluoride/Density of air = 5.09
