A molar is a form of measuring the concentrate of the acid or alkali in the liquid.
If we have 50cm3 of hydrochloric acid and 50cm3 of sodium hydroxide and if the molars were the same we would need the same amount of each to neutralize the other. So we would need to use 50m3
If the hydrochloric acid was 0.5 molars:
With 50 cm3 of HCl we would need 25cm3 of sodium hydroxide (that is still at 1 molar)
With 100 cm3 we would need to use 50cm3
If we had 40cm3 of HCl at 0.5 molars and 30cm3 of NaCL at 1 molar we would have a slightly alkaline solution (pH 9-10)
