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:

1797.6 mmHg

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

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

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

We have

[tex]P_2 = \frac{27 \times 759}{11.4} = \frac{20493}{11.4} \\ = 1797.631....[/tex]

We have the final answer as

1797.6 mmHg

Hope this helps you
