Question

The rate of diffusion of sample of ozonised oxygen(o3+o2) is 0.98 times that of pure oxygen. The percentage by volume of ozone in the ozonised sample is

Answer 1

is 0.98 times more than that of pure oxygen. Find the percentage (by volume) of ozone in the ozonised sampl

Answer 2

Let, the volume of O

at STP will weight 48 g and 32 g respectively.

The weight of x mL of O

(600−x)×32

=1.0.

∴x=200 mL
