Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose, in the mixture, the volumes of oxygen and hydrogen are 
and 
, respectively. If the densities are 
and 
, respectively, then their masses will be 
and 
, respectively. If the density of the mixture is 
, then
Given: 
,
Let 
be the speed of sound in the mixture and 
in hydrogen. Then by Laplace's formula, we have
