Answer:
450 L
Explanation:
Because you are dealing with pressure and volume, you want to use Boyle's Law to find your missing value. The equation looks like this:
P₁V₁ = P₂V₂
In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and temperature. To find the final volume, you can plug the given values into the equation and simplify.
P₁ = 150 pKa P₂ = 250 pKa
V₁ = 750 L V₂ = ? L
P₁V₁ = P₂V₂ <----- Boyle's Law equation
(150 pKa)(750 L) = (250 pKa)V₂ <----- Insert variables
112500 = (250 pKa)V₂ <----- Multiply 150 and 750
450 L = V₂ <----- Divide both sides by 250
