a solution containing 13.75g of barium hydroxide is to be neutralized with a 0.150 mol/L phosphoric acid solution. what volume of the acid solution will be required?

Answer 1

1. Write and balanced the equation.
2. Convert 13.75 g Ba(OH)2 to mols. mols = grams/molar mass = ?
3. Using the coefficients in the balanced equation, convert mols Ba(OH)2 to mols H3PO4.
4. Now convert mols H3PO4 to the volume needed. M = mols/L. You have M and mols, substitute and solve for L. Convert to mL if needed.
