Question

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 :, 9 4 R, 7 4 R, 3 2 R, 5 2 R

MARKS App · Accepted Answer

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
