The density of a gas is found to be `1.56 g L^(-1)` at `745 mm` pressure and `60^(@)C`. Calculate the molecular mass of the gas.

Explanation

To calculate the molecular mass of the gas using the given density, pressure, and temperature, we can follow these steps:

### Step 1: Write down the Ideal Gas Equation
The ideal gas equation is given by:
\[ PV = nRT \]
Where:
- \( P \) = pressure
- \( V \) = volume
