Question

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 the the reaction uses (0.100 mol) (77.083 g/mol) = 7.71 g of ammonium acetate, which has

(7.71) (6.022 x 10^23) = 4.64 x 10^24 molecules
In one sentence explain the mistake that the student made and determine the correct number of molecules of ammonium acetate used in the reaction

Answer 1

The student made the mistake of not converting the molar mass of ammonium acetate into grams before calculating the number of molecules, so the correct number of molecules used in the reaction is actually (0.100 mol) (77.083 g/mol) (6.022 x 10^23) = 4.64 x 10^24 molecules.
