from Graham's law of diffusion of gas,
rate of diffusion ∝ 1/√(molecular weight)
i.e.,
a/c to question, rate of diffusion of unknown gas , X is 1.73 times smaller than rate of diffusion of oxygen.
i.e.,
or,
or,
molecular weight of oxygen, = 32g/mol
now,
squaring both sides,
or, 1/3 = 32/
or, = 32 × 3 = 96 g/mol.
hence, molecular mass of unknown gas is 96 g/mol.
Answer:
96g
