Question

A 9.0 mL sample of oxygen gas (Q) is stored at a pressure of 6.3 atm. If the pressure of the sample

is decreased to 2.4 atm, what will the new volume be?

Answer 1

The answer is 23.63 mL

Step-by-step explanation:

In order to find the new volume we use 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) \\`

From the question

P1 = 6.3 atm

V1 = 9 mL

P2 = 2.4 atm

So we have

`V_2 = (6.3 * 9)/(2.4) \\ = 23.625`

We have the final answer as

23.63 mL

Hope this helps you
