Problem: A gas sample has an initial pressure of 571 mmHg and an initial volume of 0.526 L .What is the pressure (in atm) when the volume of the sample is decreased to 226 mL ? (Assume constant temperature and constant number of moles of gas.)

FREE Expert Solution

The initial and final pressure and volume of the gas are related by Boyle’s Law:


P1V1=P2V2


We can use Boyle’s law as long as the units for the initial and final values are the same.


We can rearrange the combined gas law to solve for P2:


P2=P1V1V2
