Question

A gas has a volume of 300 mL and a pressure of 2 atm. What volume will the gas occupy when the pressure is

increased to 7 atm (total)?

Answer 1

The answer is 85.71 mL

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`

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new volume

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

We have

`V_2 = (300 * 2)/(7) = (600)/(7) \\ = 85.714285...`

We have the final answer as

85.71 mL

Hope this helps you
