Question

a mixture of Oxygen and nitrogen is given whose density is 1.3gr/l. find partial pressure of Oxygen​

Answer 1

Explanation:

Let Imol of gas is present, so, 22 .4I will be volume of the mixture

% of O2 present in mixture=X

% of nitrogen present in mixture = 1-x

Molar mass of oxygen & nitrogen are 32 & 28g/mol respectively

32(x)+28(1-x) =29.12

x-O.28

partial pressure of o2 is 0.28 atm
