# What is the volume expressed by a gas at an half atmosphere pressure..?

Solve the Ideal Gas equation for the different molar quantities, and of course you must specify a standard temperature........

#### Explanation:

We assume a molar quantity of gas, and we also assume ideality.

${V}_{n} = \frac{n R T}{P} = \frac{1 \cdot m o l \times 0.0821 \cdot \left(\frac{L \cdot a t m}{K \cdot m o l}\right) \times 298 \cdot K}{0.5 \cdot a t m}$

$= 48.9 \cdot L$

So substitute in the other $P$ values...........
