A student obtained 3.7g of methyl cinnamate (162g/mol) from 6.5g of cinnamic acid (148g/mol) and 2.0g of methanol (32g/mol). Determine which reagent is limiting and calculate the percentage yield achieved by the student.

Reaction equation:cinnamic acid + methanol --> methyl cinnamate (+ water).Determine the limiting reagent:Calculate the number of moles of each reagent using the triangle g/(GFM)*(n).n = g/GFM cinnamic ...
