Question

A gaseous mixture containing 2 g H,,8 g He, 22 g Co, and 8 g 0, is enclosed in a vessel. The gas with
highest partial pressure is
(1) He
(2) Ą
(3) CO2
(4) O₂​

Answer 1

Hi mate,

Answer:

(1)He

Explanation:

Partial pressure is determined by (Total pressure*mole fraction).

mole fraction of H2 =2/2=1

mole fraction of He=8/2=4

mole fraction of CO2=22/44=0.5

mole fraction of O2=8/32=0.25

Therefore,the substance with greater mole fraction has greater partial pressure.

I hope this answer helps!!
