Question

A sample of gas has an initial volume of 13.9 L at a pressure of 1.22 atm. If the sample is compressed to a volume of 10.3 L, what is its pressure

Answer 1

The answer is 1.65 atm

Step-by-step explanation:

The new pressure 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 pressure

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

From the question we have

`P_2 = (13.9 * 1.22)/(10.3) = (16.958)/(10.3) \\ = 1.64640776...`

We have the final answer as

1.65 atm

Hope this helps you
