A is 0.0950 moldm-3 HCl.
B is a solution containing 13.50gdm-3 of X2 CO3 .10H2 O
25cm3 of B was neutralized by 24.85 cm3 of A.
From the information provided above, calculate the
(i) Concentration of B in moldm-3
(ii) Molar mass of X2 CO3 .10H2O in gmol-1
(iii) Percentage by mass of X in X2 CO3 .10H2 O.
The equation for the reaction is
2HCl + X2 CO3 . 10H2 O 2XCl + 11H2 O + CO2?
