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 ° C is [Given R = 0 . 082   L   atm   mol - 1 K - 1 ,   T = 273   K ]

Options

  1. A2 . 518
  2. B2 . 602
  3. C25 . 18
  4. D26 . 02

Correct answer

C. 25 . 18

Step-by-step solution

Given V = 1 L , T = 273 K ,   R = 0 . 082 ,   P T = ? and n T = 4 32 + 2 2 = 9 8 We know that: P T V = n T   RT Ideal Gas equation. Now putting the values P T = 9 8 × 0 . 082 × 273 = 25 . 18   atm
