A gas mixture contains `160g` `O_(2)` and `320g` `O_(3)` .The molar ratio of `O_(3)` to `O_(2)` in the mixture will be

The vapour density of a mixture containing N_(2) (g) and O_(2) (g) is 14.4. The percentage of N_(2) in the mixture is :

The vapour density of a mixture containing NO_(2) and N_(2)O_(4) is 38.3 at 27^(@)C . Calculate the mole of NO_(2) in 100 g mixture.

A mixture contains N_(2)O_(4) and NO_(2) in the ratio 2:1 by volume. The vapour density of the mixture is:

A container contains O_(2) , He and SO_(2) gases such that mass of SO_(2) is double the mass of O_(2) and mass of He is half the mass of O_(2) gas. The mole fraction of SO_(2) gas in the mixture is:

A gaseous mixture contains 1 g of H_(2) , 4 g of He , 7 g of N_(2) and 8 g of O_(2) . The gas having the highest partial pressure is :-

A mixture of gases contains H_(2) and O_(2) gases in the ratio of 1:4 (w//w) . What is the molar ratio of the two gases in the mixture?
