If you start with 1.00 g NaCl and an excess of the other reactants, how many grams of Cl2 will be produced?

Answer 1

Convert 1.00 g NaCl to mols. moles = grams/molar mass

Using the coefficients in the balanced equation, convert moles NaCl to moles Cl2.

Now convert moles Cl2 to grams. g = moles x molar mass.
