Question

A sample of gas has a volume of 5.58 l at a pressure of 715 mm hg. what is the volume of the gas when the pressure of the gas is increased to 755 mm hg?

Answer 1

The volume of the gas when the pressure of the gas increases to 755mm hg is calculated as follows

by use of boyles law formula that P1v1=P2V2
V2= P1V1/P2
V1=5.58 L
P1= 715 mm hg
P2=755 mm hg
V2 is therefore= ( 715 mm hg x 5.58 L) /755 mm hg= 5.28 L
