A is 0.0950moldm^3 HCl B is a solution containing 13.50gdm^-3 of X2CO3.10H2O. Take the volume of A to be 24.60cm^3 and volume of B to be 25.00cm^3, calculate
(i) concentration of B in moldm^-3
(ii)molar mass of 10H2O in gmol^-1
(iii)percentage by mass of X in X2CO3 [H=1, C=12, O=16]
the equation for the reaction is
2HCl(aq)+X2CO3.10H2O------->
2XC(aq)+11H2O+CO2(aq)?
