When 9.08 times 10^5 grams (one ton) of sodium chloride are electrolyzed in the commerical production of Chlorine, 5.24 times 10^5 grams of Chlorine are produced: 2 NaCl (aq) + 2 H2O (l) >>H2 (g) + Cl2 (g) + 2 NaOH (aq). Calculate the percentage yield.
% yield = (experimental yield/theoretical yield) x 100%
experimental yield is the mass obtained during electrolysis.
to determine the theoretical yield, you have to find the limiting agent from the balanced equation, then use its mole to determine the mole for Chlorine. Then convert that mole for chlorine to grams and plug it in in the % yield equation.
