Question

A gas occupies a volume of 120 mL at 700 mm Hg. What will happen to the volume of the gas if the pressure is changed to 1500 mm Hg at constant temperature

Answer 1

Answer:

56 mL

Explanation:

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

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

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

$V_2 = \frac{700 \times 120}{1500} = \frac{84000}{1500} = \frac{840}{15} \\ = 56$

We have the final answer as

56 mL

Hope this helps you
