How to solve gas law equations

Boyle's law

p1v1 = p2v2

P1 = the pressure of the gas @ the initial volume

V1 = the initial volume of gas

P2 = the pressure of gas at the final volume

V2 = the final volume of gas

List the known variables and the unknown variable

Rearrange the equation to isolate the unknown

Substitute the known values in the equation and solve

Example (use your own data for your situation)

5L of a gas @ a temp of 24C is 105 Kpa. What will ...
