A gas is placed in a 5.0-mL syringe. It exerts 127 mm Hg of pressure on the inside walls of the syringe. The syringe's plunger is pressed, reducing the volume of the syringe to 2.4 mL. The cap was not removed from the syringe, so none of the gas escapes. Assuming the temperature of the gas does not change, use Boyle's law to determine the pressure of the compressed gas.

Answer:264.58 mm of Hg

Step-by-step explanation:

Given

Volume of gas
V_1=5\ mL

Pressure
P_1=127\ \text{mm of Hg}

If the Plunger is pressed volume is reduced to


V_2=2.4\ mL

As temperature of the gas does not change so it follows boyle's law

According to which


P_1V_1=P_2V_2


127* 5=P_2* 2.4


P_2=264.58\ \text{mm of Hg}
