1. The problem statement, all variables and given/known data
"Use your experimental data to calculate the formula for hydrated MgSO4"

2. Relevant equations
i used 2.25g x 1 mole/141.46 = 0.016 moles



3. The attempt at a solution
i'm not sure how to calculate the formula. how do i do that? is there a different equation involved?
please reply, i really need help.

assume that your product is pure MgSO4. You know the mass and FW. Calculate moles. The difference in wt betwieen starting material and product represents what?
