Question

A gas occupies 20 liters at a pressure of 40.0 mm hg. What is the volume when the pressure is increased to 80.0 mm hg?

Answer 1

10 L

Step-by-step explanation:

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

`P_1V_1 = P_2V_2`

From the question we have

`V_2 = (P_1V_1)/(P_2) \\`

From the question we have

`V_2 = (40 * 20)/(80) = (800)/(80) = 10 \\`

We have the final answer as

10 L

hope this helps you
