A solid has a volume of 218 cm³ and a mass of 0.0179 kg. Express your answer with the appropriate units and number of significant figures.

A. Density = 0.082 g/cm³
B. Density = 0.0820 g/cm³
C. Density = 8.2 x 10⁻² g/cm³
D. Density = 8.20 x 10⁻² g/cm³

Answer :

Final answer:

The density of the solid is 0.082 g/cm³.

Explanation:

The density of a substance is the ratio of the mass of a sample of the substance to its volume. In this case, the mass is 0.0179 kg and the volume is 218 cm³. To find the density, we divide the mass by the volume:

Density = 0.0179 kg / 218 cm³

Converting the mass to grams (since the volume is in cm³), we have:

Density = 17.9 g / 218 cm³

And simplifying the expression gives us the answer:

Density = 0.082 g/cm³
