At 1.70 atm, a sample of gas takes up 4.25L. If the pressure in the gas is increased to 2.40 atm, what will the new volume be?

Answer:

This question is an example of Boyle's gas law which states that the pressure of a given mass of a gas is inversely proportional to its volume at a constant temperature. The formula for this gas law is:

P1·V1 = P2·V2

P1 = initial pressure = 1.7 atm

V1 = initial volume = 4.25 L

P2 = final pressure = 2.4 atm

V2 = final volume = ?

Rearrange the formula to isolate V2. Substitute the known data and solve.

V2 = P1·V1/P2

V2 = 1.7 atm·4.25 L/2.4 atm = 3.0 L to two significant figures

The new volume will be ~3.0 L.
