Answer:
.0388 atm
Explanation:
Since temperature is not given , we assume that it is constant . So we can apply Boyle's law . According to it
P₁ V₁ = P₂ V₂
P₁ and V₁ are pressure and temperature initially and P₂ and V₂ are pressure and volume finally .
Putting the given values
.12 x 2.31 = 7.14 x P₂
P₂ = .12 x 2.31 / 7.14
= .0388 atm .
