# What pressure is exerted by a mass of 1*g nitrogen gas that is contained in a 0.50*L volume under standard conditions?

Well, the mass is easy as you have specified it.....

#### Explanation:

If the dinitrogen is at room temperature, $298 \cdot K$, you could also specify the pressure by means of the ideal gas equation:

$P = \frac{n R T}{V} = \frac{\frac{7 \cdot g}{28.02 \cdot g \cdot m o {l}^{-} 1} \times 0.0821 \cdot \frac{L \cdot a t m}{K \cdot m o l} \cdot \times 298 \cdot K}{0.50 \cdot L}$

$\cong 12 \cdot a t m$

Note that $1 \cdot L \equiv 1 \cdot {\mathrm{dm}}^{3}$, and I can use these units interchangeably.1
