The molar concentration C (M) shows how many moles of a solute are contained in 1 liter of solution.
Normal concentration C (n) is the number of equivalents of a given substance in 1 liter of solution.
For KOH, C (M) and C (n) will be equal.
C (KOH) = V * W * p / Mr = 1000 * 0.02 * 1.01 / 56 = 0.36 mol / l or mol * eq / l.
