"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 gas volume is 50.0 mL when two weights are present. Predict the new gas volume when four more weights are added." So how exactly would I go about doing this? I want to understand it completely so I can pass my next quiz.

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass
