# How many moles of gas occupy 98 L at a pressure of 2.8 atmospheres and a temperature of 292°K?

Jun 18, 2018

${n}_{\text{gas}} \cong 11 \cdot m o l$

#### Explanation:

We solve for $n$ in the Ideal Gas equation...

$n = \frac{P V}{R T}$

$= \frac{2.8 \cdot a t m \times 98 \cdot L}{0.0821 \cdot L \cdot a t m \cdot {K}^{-} 1 \cdot m o {l}^{-} 1 \times 292 \cdot K}$

$\cong 11 \cdot m o l$...
