For a gas having molar mass M, specific heat at constant pressure per gm of gas is given by:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The correct answer is Option A because it correctly calculates the specific heat at constant pressure per gram of gas using the given formula. Options B, C, and D are incorrect as they do not provide the correct calculation and are therefore not the right choices.
