# What is the pressure in 2 L balloon which contains 5 moles of gas at a temperature of 250 K?

$51.3 \text{ atm}$

#### Explanation:

This is the ideal gas law: $P V = n R T$

We can rearrange to solve specifically for pressure: $P = \frac{n R T}{V}$

$n = \text{moles} = 5$
$R = \text{ideal gas constant} = 0.8206$
$T = \text{temperature in Kelvin} = 250$
$V = \text{volume in liters} = 2$

Plug in these values to find an answer of $51.3 \text{ atm}$.
