The molar mass of ammonium acetate is 77.083 g/mol. A student uses 0.100 mol of ammonium acetate in a chemical reaction. The student claims that the reaction uses
(0.100 mol) (77.083 g/mol) = 7.71 g of ammonium acetate, which has
(7.71) (6.022 × 1023) = 4.64 x 1024 molecules.In one to two sentences, explain the mistake that the student made and determine the correct number of molecules of ammonium acetate used in the reaction.
