Two vessels A and B are of the same size and are at same temperature. A contains 1 g of hydrogen and B contains 1 g of oxygen. P A and P B are the pressures of the gases in A and B respectively, then P A P B is :

Options

  1. A16
  2. B8
  3. C4
  4. D32

Correct answer

A. 16

Step-by-step solution

For both the gases, it follows that P A V A P B V B = n A R T A n B R T B . . . 1 Given V A = V B and T A = T B . Thus, from equation (1), it follows that P A P B = n A n B = 1 2 1 32 = 16
