Question:

A sample neon gas occupies a volume of 2.8L at 1.8atm. What will its volume be at 1.2atm?

Solution:

By the Boyle’s law we have:

$$P _ {1} \cdot V _ {1} = P _ {2} \cdot V _ {2},$$

Therefore, $V_{2} = \frac{P_{1} \cdot V_{1}}{P_{2}} = \frac{1.8 \text{atm} \cdot 2.8 \text{L}}{1.2 \text{atm}} = 4.2 \text{L}$ .

Answer:

$$V _ {2} = 4.2 \text{L}.$$
