A clear, colorless solution of chemical A and a colorless, but cloudy suspension of chemical B had a combined total mass of 1.623 g. After mixing, the new mixture was cloudy and green and had a mass of 1.615 g. Was the Law of Conservation of Mass obeyed during this experiment? What might explain the small change in mass?
