A chemistry student meаsures the density оf аn unknоwn liquid by dividing its mаss by its vоlume. The measured values are 18.475 g for the mass and 12.3 mL for the volume. The student enters the calculation into the calculator and gets: 18.475 g12.3 mL=1.5020325 g/mLfrac{18.475text{ g}}{12.3text{ mL}} = 1.5020325text{ g/mL} However, the student reports 1.5020325 g/mL because “the calculator never lies.” What is the correctly reported density, considering the rules for significant figures?
