February 22nd, 2020

A is a solution containing 3.5g of an acid Hx per dm3
B is a solution containing 0.50mole of anhydrous Na2CO3 per dm3 of solution. 25cm3 portions of solution B required an average volume of 26.10cm3 of solution A for complete neutralization. From these results, calculate
a. Molar concentration of solution A
b. The relative molecular mass of A
