56.0 g of nitrogen and 48.0 g of `O_(2)` are mixed together in a vessel at a temperature of 300K and a pressure of one atmosphere . Assuming the gases to be ideal, find the density of the mixture.

Explanation

To find the density of the mixture of nitrogen and oxygen gases, we can follow these steps:

### Step 1: Calculate the total mass of the gas mixture.
The total mass of the gas mixture is the sum of the masses of nitrogen and oxygen.

\[ \text{Total mass} = \text{mass of } N_2 + \text{mass of } O_2 = 56.0 \, \text{g} + 48.0 \, \text{g} = 104.0 \, \text{g} \]
