A closed container of volume 0.02m³ contains a mixture of neon and argon gases, at a temperature of 27°C and pressure of 1 × 10⁵ Nm^-2 . The total mass of the mixture is 28g. If the gram molecular weights of neon and argon are 20 and 40 respectively. Find the masses of the individual gases in the container, assuming them to be ideal. (Universal gas constant R = 8.314 J/mol.k)

• A

  ${\mathrm{m}}_1=4\mathrm{g},{\mathrm{m}}_2=24\mathrm{g}$

• B

  ${\mathrm{m}}_1=8\mathrm{g},{\mathrm{m}}_2=20\mathrm{g}$

• C

  ${\mathrm{m}}_1=16\mathrm{g},{\mathrm{m}}_2=12\mathrm{g}$

• D

  ${\mathrm{m}}_1=12\mathrm{g},{\mathrm{m}}_2=16\mathrm{g}$
