Moleculer weight = (wt/molarity)*(1/Vol in lt)

                          = (52/0.0366)*(1/1)

                           = 1420.76

Unhydrated Na2CO3 mol.wt is = 106 gm/mol

Subtract Unhydrated moleculer weight from hydrated moleculer weight

                = 1420.76 - 106 = 1314.76

Divide the above value with moleculer weight of water

                          = 1314.76/18.015 = 72.98

so no.of H2O molecules are 73

the formula is Na2CO3 73*H2O
