Q: 2 NH_3 + 3 CuO -----> N_2 + 3 Cu + 3 H_2O

{a} g of NH_3 reacts with excess CuO to produce 6.63 g of N_2. What is the percent yield of N_2?
A: 806.389721627/{a} (formula; values not in the backup's text)

Q: P_4 + 6 F_2 -------> 4 PF_3

How many g of PF_3 will be produced if {a} g of F_2 react, and the reaction has a 78.1% yield?
A: 1.205343333*{a} (formula; values not in the backup's text)

Q: Ag_2O + C_10H_10N_4SO_2 ------> AgC_10H_9N_4SO_2 + H_2O

The reaction is carried out in the laboratory and the amount of AgC_10H_9N_4SO_2 obtained is 120.5 g. If the theoretical yield was {a}, what is the percent yield of AgC_10H_9N_4SO_2?
A: 12050/{a} (formula; values not in the backup's text)
