What is the pressure of a $2 L$ container containing $2.36 m o l$ of $C {O}_{2}$ at ${26}^{o} C$?

#### Explanation:

This is a pretty standard kind of question where you're given some information and left with one variable to solve for. It is imperative that you are familiar with the equation $P V = n R T$.

A lot of times you will be given the temperature in Celsius, in that case you need to convert to Kelvin by adding 273.

With some simple algebraic manipulation one can isolate the variable $P$ and solve.

$P = \frac{\left(2.36 m o l\right) \left(0.8026 \frac{L \cdot a t m}{m o l \cdot K}\right) \left(299 K\right)}{2 L}$
