`2 mol` `'H_(2)` is mixed with `2 gm ` of `H_(2)`. The molar heatr capacity at constant pressure for the mixture is

Options

A. `(17R)/(6)`
B. `(11R)/(6)`
C. `4R`
D. `(3R)/(2)`

Explanation

To solve the problem of finding the molar heat capacity at constant pressure (Cp) for the mixture of 2 moles of helium (He) and 2 grams of hydrogen (H₂), we can follow these steps:

### Step-by-Step Solution:

1. **Convert grams of Hydrogen to moles**:
- The molar mass of hydrogen (H₂) is approximately 2 g/mol.
- Given mass of hydrogen = 2 g.
- Moles of hydrogen = mass / molar mass = 2 g / 2 g/mol = 1 mole.
