Answer:
156 mL will be the new volume of the shape
Explanation:
First of all, we need to convert the Torr to atm.
1220 Torr . 1 atm / 760 Torr = 1.60 atm
When the temperature remains constant, it is satisfied that the volume is modified indirectly proportionally.
Pressure is increased, then volume decreases
Pressure is decreased, then volume increases
P₁ . V₁ = P₂ . V₂
0.768 atm . 325mL = 1.60 atm . V₂
V₂ = 0.768 atm . 325mL / 1.60 atm → 156 mL
