Percent yield: In an actual experiment, the yield of product can be lower than what you would expect from the stoichiometry of a balanced equation. Percent yield allows us to measure the experimental etficiency of a reaction, it is given by: Theoreticalyieldofproduct(fromabalancedeq)Actualyieldofproduct(exporimentalyield)100 Percent yield can be computed in terms of moles of product and reactant or, if molar masses are given, using grams of product and reactant. This is an example calculating w yield using 9 rams and combining the idea of limiting reactant. Molar masses are as follows: A=45.829;B=52.82;C=65.959,D=94.00g Consider the balanced equation: 2A+5B3C+D 3.86gA are maxed with 7.72gB at an elevated temperature. If the mass of C produced is 3.59g, what is the percent yield
