1.3.2 g of hydrated sodium carbonate, Na2CO3.xH2O, was dissolved in water and the resulting solution was titrated against 1.0 moldm-3 hydrochloric acid. 22.4 cm3 of the acid was required. What is the value of x?

Please help?

Work out moles of acid, use the stoichiometric ratios to determine moles of hydrous sodium carbonate. Use relevant equation to work out Mr and using the Ars you know, you can workout x.
