8.00*g of what? Sodium hydroxide?

Explanation:

We can guess that you mean "1 US gallon"-=3.785*L. We cannot guess the solute. Would you review this question?

If the solute is sodium hydroxide, then,

[NaOH]="Moles of NaOH"/"Volume"

=((8.00*g)/(40.00*g*mol^-1))/(1.0*"gallons"xx3.785*L*"gallon"^-1)

5.28xx10^-2*mol*L^-1 with respect to NaOH.

So [Na^+]=[HO^-]=5.28xx10^-2*mol*L^-1.

What is the pH of this solution?
