Question

Hydrogen effuses four times more rapidly than
volume of an unknown gas molar mass of
unknown gas should be
A. 16 gmol' B. 32 gmol"
C. 48 gmol' D. 64 gmol'
(With solution??)

Answer 1

Answer:

twenty five percent said they are the answer of this question is the

Answer 2

Answer:

the molar mass of the gas is 32g/mol. So the gas is O2.

Explanation:

Let

r'= rate of effusion of H2=4times. and molar mass of H2=2g/mol

r"=rate of unknown gas=1time w.r.t H2.

As,

r'/r"=√M"/√M'

4/1=√M"/√2

16/1=M"/2

M"=32g/mol
