Choose the correct option for the total pressure (in atm.) in a mixture of 4 g

O_2

and 2 g

H_2

confined in a total volume of one litre at

0^\circ C

is: [Given R = 0.082 L atm

mol^{-1} K^{-1}

T = 273 K] 26.02 2.518 2.602 25.18

Step-by-Step Verified Solution

n O 2 = 4 32 = 1 8 n H 2 = 2 2 = 1 n t = 1 8 + 1 = 9 8 P t V = n t R T P t = 9 8 _ 0.082 _ 273 1 = 25.18 atm
