At which of the following four conditions will the density of nitrogen be the largest?

Options

A. `STP`
B. `273 K` and `2 atm`
C. `546 K` and `1 atm`
D. `546 K` and `2 atm`

Explanation

To determine the condition under which the density of nitrogen gas is the largest, we can follow these steps:

### Step 1: Understand the Ideal Gas Law
The ideal gas law is given by the equation:
\[ PV = nRT \]
where:
- \( P \) = pressure
- \( V \) = volume
