A hydrate 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
