Question

A

A sample of gas has a volume of 3.50 L and a pressure of
125 mm Hg. What will the new pressure be when the volume
is decreased to 2.75 L? The temperature stays the same.

Answer 1

159.09 mmHg

Step-by-step explanation:

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

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

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

`P_2 = (125*3.50 )/(2.75) = (437.5)/(2.75) \\ = 159.090909...`

We have the final answer as

159.09 mmHg

Hope this helps you
