Question

The mass of a cylinder was determined on an analytical balance to be 50.208 g. The volume of the cylinder was measured and determined to be 5.6 mL. The density of the metal cylinder, expressed to the proper number of significant figures, is
Options
A 8.9657 g/mL
B 9.0 g/mL
Correct Answer
C 0.11153 g/mL
D 0.11 g/mL
Correct Answer

Option B is the correct answer.

Detailed Explanation

Density = mass/volume = 50.208 g / 5.6 mL = 8.9657 g/mL. Volume has 2 significant figures, so the answer should have 2 significant figures: 9.0 g/mL.

Hint

The result should have the same number of significant figures as the least precise measurement.
