Specific heat of constant pressure of a diatomic gas having molar mass `M` is approximately equal to

Options

A. `(gamma R)/(M(gamma-1))`
B. `(gamma)/(RM)`
C. `(M)/(R(gamma-1))`
D. `(gamma RM)/(gamma +1)`

Explanation

To find the specific heat at constant pressure (\(C_p\)) of a diatomic gas with a molar mass \(M\), we can follow these steps:

### Step 1: Use the relationship between \(C_p\) and \(C_v\)
For any ideal gas, the relationship between the specific heats at constant pressure and constant volume is given by:
\[ C_p - C_v = R \]
where \(R\) is the universal gas constant.
