50.0g of Sulphur is mixed with 100.0g of iron and heated strongly. When the reaction is complete 12.5g of iron remains. What is the formula of the sulphide formed?

What i have done so far is i got the 2 mols of each element.

Fe=1.79

S=1.56

i divided biggest/smallest and i get 1.41

now i need to know how to put it in ratio form and what to do to find the formula for Sulphide
