Question

A gas starts at a volume of 23 L and a pressure of 1.23 atm. What is the new pressure if you

change the volume to 15 L?

Answer 1

1.89 atm

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 = (1.23 * 23)/(15) = (28.29)/(15) \\ = 1.886`

We have the final answer as

1.89 atm

Hope this helps you
