Answer:
A gas that exerts a pressure of 14 bar  in a container with a volume of 312 mL will exert a pressure of 6.7 bar when transferred to a container with a volume of 652 mL.
Explanation:
Given data;
Initial pressure = 14 bar
Initial volume  = 312 mL
Final pressure = ?
Final volume = 652 mL
Solution:
PâVâ = PâVâ
Pâ = PâVâ Â / Vâ
Pâ = 14 bar 312 mL / 652 mL
Pâ = 4368 bar. mL /652 mL
Pâ = 6.7 bar
A gas that exerts a pressure of 14 bar  in a container with a volume of 312 mL will exert a pressure of 6.7 bar when transferred to a container with a volume of 652 mL.
