A common laboratory system to study Boyle's law uses a gas trapped in a syringe. The pressure in the system is changed by adding or removing identical weights on the plunger. The original gs volume is 50.0 ml when two weights are present. Predict the new gas volume when four more weights are added.
P1V1 = P2V2
You can use 2 as P1 and 6 as P2 or make up some number for P1 and make P2 just 3x that since 2 weights going to 6 weights is a factor of 6/2 = 3.
