Calculating Pressure using Boyle's Law

A sample of gas is contained in a sealed cylinder at a constant temperature. The initial volume of the gas is 10.0 liters and the pressure is 1.0 atm. If the volume is decreased to 5.0 liters while keeping the temperature constant, according to Boyle's Law, what will the new pressure of the gas be?

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. This relationship can be expressed with the formula: P1 * V1 = P2 * V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
