The volume V of an enclosure contains a mixture of three gases, 16 g of oxygen, 28 g of nitrogen and 44 g of carbon dioxide at absolute temperature T . Consider R as universal gas constant. The pressure of the mixture of gases is :

Options

  1. A88 R T V
  2. B3 R T V
  3. C5 2 R T V
  4. D4 R T V

Correct answer

C. 5 2 R T V

Step-by-step solution

P V = n 1 + n 2 + n 3 R T P × V = 16 32 + 28 28 + 44 44 R T P V = 1 2 + 1 + 1 R T P = 5 2 R T V
