Question:

a quantity of chlorine gas occupies a volume of 50L at 22c and 721 kPa. how many moles of chlorine gas are present?

Solution:

According to the Ideal Gas Law

$$n = PV / RT$$

Substitute values into the equation:

n = \frac{7.21 \cdot 10^{5} \text{ Pa} \cdot 5 \cdot 10^{-2} \text{ m}^{3}}{8.31 \text{ m}^{2} \text{ kg} \cdot \text{s}^{-2} \text{ \text{ \text{ } } \text{ \text{ }}^{-1} \text{ mole}^{-1} \cdot (273 + 22) \text{ K}} = 14.7 \text{ mole}

Answer: 14.7 mole.
