Report the value of gas constant in cal `K^(-1)` molecule

Explanation

To find the value of the gas constant in calories per Kelvin per molecule (also known as the Boltzmann constant), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Universal Gas Constant (R)**:
The universal gas constant (R) in calories is approximately:
\[
R \approx 1.987 \, \text{cal} \, K^{-1} \, mol^{-1}
