Given the amount of limiting regeant that you started with, how many moles of solid product did you expect to produce?
Started with 1.12g of iron
LR - iron
Equation is 2Fe + CuSo4 -> Fe2So4 + Cu
You have made a typo (maybe two typos). You mean either FeSO4 or Fe2(SO4)3 and also, the equation is not balanced. I will assume FeSO4 but if my assumption is wrong, you will need adjust the molar mass of the product accordingly. First and second, correct the products, then balance the equation.
mols Fe = grams/atomic mas = ?
Using the coefficients in the balanced equation, convert mols Fe to mols FeSO4.
Then g FeSO4 = mols FeSO4 x molar mass FeSO4
