Type: MCQ-numerical-Hard-Class 11
Given that N1/N2 = 3/2 and μ1 = m1/M1, μ2 = m2/M2, if the molecular mass M1 of gas 1 is 32 u and the molecular mass M2 of gas 2 is 28 u, what is the ratio of the masses m1/m2?
A
2
B
5
C
7
D
0
Correct Answer
Option A
Detailed Explanation
From μ1/μ2 = N1/N2 = 3/2 and μ = m/M, we have (m1/M1)/(m2/M2) = 3/2. Substituting M1 = 32 and M2 = 28, we find m1/m2 = (3/2) * (32/28) = 1.2.
