CHEM 161 EXAM 2 Answers actual yield the experimental quantity, in grams, of product obtained in a reaction. Avogadro’s number the number of particles (6.022 x 10^23) of a substance in 1 mol of that substance. By definition, Avogadro’s number is equal to the number of carbon-12 atoms in exactly 12.00 g of carbon-12. balanced appropriate coefficients have been added such that the number of atoms of each element are the same in both reactants and products. chemical equation a prec...
