A solution containing 3.00 g of a monobasic organic acid was just neutralised by 40 mL of 05 N NaOH solution. Calculate the molecular weight of the acid.

12.5 mL of a solution containing 6.0 g of a dibasic acid in 1 L was found to be neutralized by 10 mL a decinormal solution of NaOH . The molecular weight of the acid is

1.25g of a solid dibasic acid is completely neutralised by 25mL of 0.25 molar Ba(OH_(2)) solution. Molecular mass of the acid is:
