Using the equation of state `pV=nRT`, show that at a given temperature the density of gas is proportional to gas pressure `p`.

Explanation

To show that at a given temperature the density of a gas is proportional to its gas pressure using the ideal gas equation \( pV = nRT \), we can follow these steps:

### Step-by-Step Solution:

1. **Start with the Ideal Gas Equation**:
\[ pV = nRT \]
