Two mole of oxygen is mixed with eight mole of helium. The effective specific heat of the mixture at constant volume is

Options

  1. A1.3 R
  2. B1.4 R
  3. C1.7 R
  4. D1.9 R

Correct answer

C. 1.7 R

Step-by-step solution

For mixture of gases, C_V= n₁ (C_V )₁+n₂ (C_V )₂ n₁+n₂ Here, (C_V )₁= 5 2 R, (C_V )₂= 3 2 R C_V= 2 5 2 R+8 3 2 R 2+8 = 17 10 R=1.7 R
