Question

What pressure must be used to compress 850 mL of argon gas at 146 kPa to 150 mL? (Temperature is held constant.)

Answer 1

Boyle's law states the relationship between pressure and volume of a gas.
At constant temperature, pressure of a gas is inversely proportional to its volume.
PV = k
P - pressure, V - volume and k - constant
P1V1 = P2V2
parameters for the 1st instance are on the left side and parameters for the 2nd instance are on the right side
146 kPa x 850 mL = P2 x 150 mL
P2 = 827.33 kPa
