Two moles of a monoatomic gas is mixed with six moles of a diatomic gas. The molar specific heat of the mixture at constant volume is :

Options

  1. A9 4 R
  2. B7 4 R
  3. C3 2 R
  4. D5 2 R

Correct answer

A. 9 4 R

Step-by-step solution

For mixture of gases, we can write C v = n 1 C v 1 + n 2 C v 2 n 1 + n 2 = 2 × 3 2 R + 6 × 5 2 R 2 + 6 = 9 4 R
