The volume that will this gas have at 1.00 atmosphere pressure is 254.6. The volume is 254.6.
Boyle's law says that the volume of a gas at constant temperature varies with varying pressure.
The formula is
P1 V1 = P2 v2
P1 = 645
P2= 1.00 = 760 mmhg
V1 = 300 ML
V2 =?
Putting the value in the equation
645 x 300 = 760 x V2 =
V2 = 254.6
Thus, the volume is 254.6.
