Question

A gas has a volume of 240mL at 700mmHg pressure. What pressure is needed to reduce the volume to 80mL?

Answer 1

Answer:

The answer is 2100 mmHg

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new pressure

$P_2 = \frac{P_1V_1}{V_2}$

From the question we have

$P_2 = \frac{240 \times 700}{80} = \frac{168000}{80} = \frac{16800}{8}$

We have the final answer as

2100 mmHg

Hope this helps you
