Two vessels separately contain two ideal gases 
and 
at the same temperature, the pressure of 
being twice that 
. Under such conditions, the density of 
is found to be 1.5 times the density 
. The ratio of molecular weight 
and 
is
A
2

Text Solution
Verified by ExpertsThe correct answer is:
D
According to an ideal gas equation, the molecular weight of an ideal gas is
where 
and 
are the pressure, temperature and density of the gas respectively and 
is the universal gas constant.
The molecular weight 
is
and that of 
is 
Hence, their corresponding ratio is
Here,
