Answer:
6.85g/mol
Explanation:
According to the Graham's law of diffusion,the rate of diffusion is inversely proportional to the square root of molecular mass.
k=r√m.m
k=constant
r=rate of diffusion or effusion
m.m=molecular mass
taking ''1'' and '2" to be the two gases 1=oxygen,2=unknown gas
r1√m1=r2√m2,molar mass of oxygen=16
mathematically√m2=229√16/350
√m2=2.617
m2=6.85g/mol
