The molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.

How to calculate molarity?

The molarity of a solution can be calculated using the following formula:

CaVa = CbVb

Where;

  • Ca = concentration of acid
  • Cb = concentration of base
  • Va = volume of acid
  • Vb = volume of base

60 × 0.0100 = 30 × Cb

0.6 = 30Cb

Cb = 0.6/30

Cb = 0.02M

Therefore, molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.
