    Sodium carbonate exists in hydrated form, Na2CO3.xH2O, in the solid state. 3.5 g of a sodium carbonate sample was dissolved in water and the volume made up to 250 cm3. 25.0 cm3 of this solution was titrated against 0.1 moldm-3 HCl and 24.5 cm3 of the acid were required. Calculate the value of x given the equation:
    Na2CO3 + 2HCl  2NaCl + CO2 + H2O
    could someone answer this with working out please, thanks

    What have you tried so far?
    It might help to concisely list the values you have so that you use them for your calculations.
