A closed container of volume `0.02m^3`contains a mixture of neon and argon gases, at a temperature of `27^@C` and pressure of `1xx10^5Nm^-2`. The total mass of the mixture is 28g. If the molar masses of neon and argon are `20 and 40gmol^-1` respectively, find the masses of the individual gasses in the container assuming them to be ideal (Universal gas constant `R=8.314J//mol-K`).

Options

A. `m_(1) = 4 g, m_(2) = 24 g`
B. `m_(1) = 8 g, m_(2) = 20 g`
C. `m_(1) = 16 g, m_(2) = 12 g`
D. `m_(1) = 12 g, m_(2) = 16 g`

Answer

A

Explanation

`n = n_("ne") + n_(Ar) , m_(me) = m , m_(Ar) = 28 m`
