Question 1: In a filtration experiment 25 cm³ of a solution of Sodium Hydroxide containing 1 litre was required for complete neutralization of 0.245 g of a dibasic acid

Here's a step-by-step solution for question 1:

Question 1: In a filtration experiment $25 \text{cm}^3$ of a solution of Sodium Hydroxide containing $1 \text{litre}$ was required for complete neutralization of $0.245 \text{g}$ of a dibasic acid. Calculate the relative molecular mass of the acid (Na = 23.0, O = 16, H = 1).

The phrasing "a solution of Sodium Hydroxide containing 1 litre" is ambiguous. We will assume it means the concentration of the Sodium Hydroxide solution is $1 \text{ mol/L}$ (i.e., $1 \text{ mole}$ of $\text{
