An unknown gas 'X' diffuses four times as quickly as oxygen. The molar – InterviewSolution

1.	An unknown gas 'X' diffuses four times as quickly as oxygen. The molar mass of the unknown gas is :
Answer» 2 64 4 32 Solution :If rate of diffusion of `O_(2)` is X, then rate of diffusion of UNKNOWN gas is 4x. `( 4x)/( x)= SQRT(( 32)/( M))` or M = 2
