A sample of metal has a mass of 27.24 g and a volume of 2.20 mL. What is the correct value (correct number of significant figures) of its density using these data?

Question

Quizplus · Accepted Answer

The density is calculated by dividing mass by volume, which gives 27.24 g / 2.20 mL = 12.3818 g/mL. However, the answer must be reported with the correct number of significant figures based on the given data, which is 3 significant figures for both the mass and volume. Therefore, the correct value, rounded to 3 significant figures, is 12.4 g/mL.
