A sample of helium gas has a volume of 250.0 mL when it pressure is 0.935 atm. If the temperature remains constant, what will the pressure of the gas be when it has a volume of
175.0 mL?

The answer is

Explanation:

In order to find the volume of the gas at 175 mL we use the Boyle's law formula

That's

where

P1 is the initial pressure

V1 is the initial volume

V2 is the final volume

P2 is the final pressure.

Since we are finding the final pressure

From the question

P1 = 0.935 atm

V1 = 250.0 mL

V2 = 175 mL

Substitute the values into the above formula and solve

That's

We have the final answer as
