`2.65gm` of a diacidic base was dissolved in 500 ml of water. Twenty millilitres of this solution required 12 ml of `(N)/(6)` HCl solution. Calculate the equivalent mass and molucular mass of the base.

1.575 gm of an organic acid was dissolved in 250 ml of water Further, 20 ml of this solution required 16 ml of (N)/(8) alkali solution for complete neutralisation. If the basicity of the acid is 2, find its molecular mass.

1.26 g of a dibasic acid were dissolved in water and the solution made up to 200 mL. 20 mL of this solution were completely neutralised by 10 mL of N/5 NaOH solution. Calculate the equivalent mass and molecular mass of the acid.

7.5 g of an acid are dissolved per litre of the solution. 20 mL of this acid solution required 25 mL of N//15 NaOH solution for complete neutralization. Calculate the equivalent mass of the acid.

1.575 gm of organic acid was dissolved in 250ml of water 20ml of this solution required 16 ml of N//8 alkali solution for completely neutralization. (M. wt of acid is 126) the basicity of acid is
