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

Answer:

The answer is 23.63 mL

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

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

From the question

P1 = 6.3 atm

V1 = 9 mL

P2 = 2.4 atm

So we have

$V_2 = \frac{6.3 \times 9}{2.4} \\ = 23.625$

We have the final answer as

23.63 mL

Hope this helps you
