Question

A sample of helium gas with a volume of 27.0 mL at 759 mm Hg is compressed at a constant temperature until its volume is 11.4 mL. What will be the new pressure in the sample?

Answer 1

1797.6 mmHg

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`

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

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

We have

`P_2 = (27 * 759)/(11.4) = (20493)/(11.4) \\ = 1797.631....`

We have the final answer as

1797.6 mmHg

Hope this helps you
