A research chemist used a reaction to make an adhesive compound. The maximum theoretical mass of the adhesive compound was 18.0 g. The chemist collected all of the adhesive compound that formed, without losing any, and its mass was 14.4 g.
Using the chemist's results, calculate the percentage yield for this preparation.
Use the equation: percentage yield = (mass of adhesive compound collected / maximum theoretical mass of adhesive compound) × \times\,× 100
Give one reason why the reaction formed less adhesive compound than the maximum theoretical mass.
