PLEASE HELP I HAVE NO IDEA WHAT TO DO Use the balanced equation below to answer the question. A student begins a reaction with 200.0 grams of C7H603. Calculate the percent yield of the reaction if 231.0 grams of C9H304 is actually
produced.
C7H. O3 + C4H8O3 C9H204 + C2H4O2

The percent yield : 88.4%

Reaction

Salicylic acid (C₇H₆O₃) reacts with acetic anhydride (C₄H₆O₃) to form acetylsalicylic acid (C₉H₈O₄)

2C₇H₆O₃(aq)+C₄H₆O₃(aq)⇒2C₉H₈O₄(aq) + H₂O(l)

MW C₇H₆O₃ : 138.12 g/mol

mol C₇H₆O₃

MW C₉H₈O₄ : 180.16 g/mol

mol C₇H₆O₃ = mol C₉H₈O₄ (mol ratio from equation 2:2), so mass of C₉H₈O₄

percent yield :
