Calculate the density to the correct number of significant figures of a 100.0 g sample of mercury which occupies a volume of 7.36 cm³.

Question

Quizplus · Accepted Answer

Density is calculated as mass divided by volume. The mass is 100.0 g and the volume is 7.36 cm³, so the density is 100.0 g / 7.36 cm³ = 13.58695652 g/cm³. Rounding to the correct number of significant figures (3, based on the volume), the density is 13.6 g/cm³, which matches choice A when rounded to 4 significant figures.
