Question

A gas was held at a constant temperature in a closed system. The initial
pressure of the gas was 1.20 atm, while its initial volume was 2.30 L. The
final volume of the gas was 1.50 L. What was the final pressure of the gas
to the nearest hundredth of an atmosphere?*

Answer 1

Answer:

1.84 atm

Explanation:

P2=V1P1/V2

Temp is irrelevant because it is constant, so all you have to do is rearrange the ideal gas law.

You can check this by knowing P and V at constant T have an inverse relationship and therefore makes this the correct answer.
