Question

How many molts of H2O would be produced if 3.61 molt HCI react with an excess of Ca(OH)2?

Answer 1

What is a molt? Do you mean mol?

2HCl + Ca(OH)2 ==> 2H2O + CaCl2
3.61 mol HCl will produce 3.61 mol H2O. That's because 2 mol HCl produce 2 mols H2O (from the balanced equation).
Now convert mols H2O to g. g = mols x molar mass H2O.
