Ahydrate of iron (ii) sulfite is known to contain 44.26% mater. what is the correct name of the hydrate

The correct name of the  hydrate iron (ii) sulfite  is  iron(ii)sulfite  heptahydrate
it is gotten  as below

find the % composition  of  FeSO4  = 100-44.26 =55.74 %

find the mole of FeSO4 and  H20
= % composition/molar mass

FeSo4 =55.74/151.9 = 0.367  moles
H2O = 44.26/18 =2.459  moles

find  the mole ratio  by diving   each mole  with smallest mole
FeSO4 = 0.367/0.367 = 1
H2O = 2.459/0.367 = 7

therefore the name is iron (ii) sulfite  heptahydrate is it has  seven water  molecules
