Given the moles, we can solve for the grams of zinc sulfate:

1. 3.69 mol ZnSO4 * 161.5 g ZnSO4/mol ZnSO4 = 595.935 grams of zinc sulfate

2. 1.85 g ZnSO4 * 1 mol ZnSO4/161.5 g ZnSO4 = 0.0115 moles of zinc sulfate

Zinc Sulfate is ZnSO4 so the molar mass is 113.454g/mol. so as to discover moles we would divide the mass (4.36) via the molar mass, so the mols would cancel and we must be left with grams. EG 4.36g / 161.451g/mol = .027mol on the grounds which you have been given 4.36 you could in basic terms supply your answer to 3 significant digits so it may be .027 moles are in 4.36 grams of Zinc Sulfate

1.85/(65.38+32.06+(16*4)) Put that in your calculator and it will give you the answer.

we need to know the compound. you left that out.

extremely tough step. search in bing and yahoo. this can help!
