Question
A student measures a mass as 2.456 g and a volume as 1.2 mL. What is the density, reported with the correct number of significant figures?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Density = 2.456 g / 1.2 mL = 2.0467 g/mL. The volume (1.2 mL) has 2 significant figures, so the answer should have 2 significant figures: 2.0 g/mL.
Hint
The result should have the same number of significant figures as the least precise measurement.
