Answer #1

molar mass of chocolate = 180.08g/mole

weigh of chocolate         = 53.15g

atomicity: Total no of atoms present in a molecule is called atomicity of molecule

atomicity of chocolate C7H8N4O2   = 7+8 +4+2 = 21

no of atoms   = W* 6.023*10^23 * atomicity/G.M.Wt

                     = 53.15*6.023*10^23 *21/180.8   = 3.72*10^24 atoms >>>>>answer
