Using dimensional analysis, calculate how many mL of 0.350M KHP would react with 20.15ml of 0.189M NaOH.

Answer 1

KHP is a monoprotic acid and so 1 mole of KHP will react with 1 mole of NaOH as follows:

KHP + NaOH ==> H2O + KNaP

20.15 ml NaOH x 1 L/1000 ml x 0.189 mol NaOH/L x 1 mol KHP/mol NaOH x 1 L/0.350 mol KHP x 1000 ml/L = 10.9 mls KHP
