Complete Stoichiometry Calculations For Each Ingredient To Determine The Theoret

Complete stoichiometry calculations for each ingredient to determine the theoretical yield. what is the limiting reactant-to-excess reactant calculation for both excess ingredients?

water : 946.36g sugar: 196.86g lemon juice 2050.25g what is percent yield and left over ingredients?

I got 94.10 for percent yield and 28.12 g sugar, 177.44g water. is this correct?

Just Lemons Lemonade Recipe Equation:

2 water + sugar + lemon juice = 4 lemonade

Mole conversion factors:

1 mole of water = 1 cup = 236.59 g

1 mole of sugar = 1 cup = 225 g

1 mole of lemon juice = 1 cup = 257.83 g

1 mole of lemonade = 1 cup = 719.42 

need Help finding out calculating percent yield and left over ingredients.
