We're being asked to calculate the mass of Ca(OH)2 is required to react with the acetic acid in 25.0 mL of a solution having a density of 1.065 g/mL and containing 58.0% acetic acid by mass.

We're given the balanced reaction:         2 CH3CO2H + Ca(OH)2 ⟶ Ca(CH3CO2)2 + 2H2O

Step 1: Calculate the mass of CH3CO2H.

Recall that mass percent is given by:

Calculate the mass of the solution:

volume of solution (density) → mass solution

mass solution = 26.625 g

Calculate the mass of the CH3CO2H:
