Answer:
a. 392
Step-by-step explanation:
According to Boyles law, the pressure of a fixed mass of a gas at constant temperature is inversely proportional to the volume.
P1V1=P2V2
P1=488mm Hg
P2=757.8mm Hg
V1=609 mL
Therefore we use the values above in the formula and get:
488 mm Hg×609 mL=757.8 mm Hg×V2
V2=(488mmHg×609 mL)/757.8 mm Hg
=392.177 mL
