Question

A sample of oxygen gas occupies a volume of 5.0L at 90kPa pressure. What volume will it occupy at 145kPa?

A. 3.10
B. 5.10
C. 7.0
D. 2.5​

Answer 1

The answer is option A

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`

Since we are finding the new volume

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

From the question we have

`V_2 = (5 * 90000)/(145000) = (450000)/(145000) = (450)/(145) \\ = 3.103448...`

We have the final answer as

3.10 L

Hope this helps you
