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

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.
