2g of H₂ gas diffuses through a porous pot in 10 minutes. Under the same conditions how many grams of O₂ will diffuse through the same pot?

Molar mass of hydrogen equal to 2 grams

Molar mass of oxygen equal to 32 grams

the relationship between time and molar mass of time is inversely proportional to square root of its molar mass.

$\frac{{\mathrm{W}}_1}{{\mathrm{t}}_1}\times \frac{{\mathrm{t}}_2}{{\mathrm{W}}_2}=\sqrt{\frac{{\mathrm{M}}_1}{{\mathrm{M}}_2}}$

$\frac{2}{10}\times \frac{10}{{\mathrm{W}}_2}=\sqrt{\frac{2}{32}}$

Weight= 8 g

The required answer is D
