Question

If you have a gas that starts out with a pressure of 720 mm Hg and a volume of 1500mL, what is the new volume if you increase the pressure to 2 atm?

(Gas stoichiometry)

Answer 1

the new volume is calculated by use of Boyles law formula

that is P1V1=p2v2

v2= p1v1/p2

P1= 720 mmhg
v1= 1500ml
p2 = 2 atm
V2=?
convert P2 to mmhg = 2 x760= 1520 mmhg

V2= 720mmhg x1500 ml/ 1520mmhg = 710.53 ml
