Question

Two non-reactive monoatomic ideal gases have their atomic masses in the ratio 2:3. The ratio of their partial pressures, when enclosed in a vessel kept at a constant temperature, is 4:3. The ratio of their densities is
  1. 8 : 9
  2. 6 : 9
  3. 1 : 2
  4. 1 : 4

A
1 : 2
B
6 : 9
C
1 : 4
D
8 : 9
Solution
Verified by Toppr

The correct option is D 8 : 9
Sol : (D)
PV=nRT=mMRT

PM=ρRT

ρ1ρ2=P1M1P2M2=(P1P2)×(M1M2)=43×23=89
Here ρ1 and ρ2 are the densities gases in the vessel containing the mixture.
