# What is the pressure exerted by 1.2 mol of a gas with a temperature of 20°C and a volume of 9.5 L?

$P \cong 3 \cdot a t m$

#### Explanation:

We simply use the Ideal Gas equation...

$P = \frac{n R T}{V}$ and use an appropriate gas constant, $R = 0.0821 \cdot L \cdot a t m \cdot {K}^{-} 1 \cdot m o {l}^{-} 1$...and of course we use absolute temperature....

P=(1.2*molxx0.0821*(L*atm)/(K*mol)xx293*K)/(9.5*L)=??*atm
