Question

A student calculates the density of an unknown metal sample to be 8.25 g/cm³

Which set of data from the student's notebook correctly calculates the density of her unknown metal sample?
A. Mass = 165.2 g, Volume = 21.2 cm³
В. Mass = 198.0 g. Volume = 24.0 cm³
С. Mass = 82.5 g. Volume = 11.0 cm³
D. Mass = 202.5 g. Volume = 25.0 cm³

Answer 1

The correct set of data that correctly calculates the density of the unknown metal sample is B. Mass = 198.0 g, Volume = 24.0 cm³.

Step-by-step explanation:

The correct set of data that correctly calculates the density of the unknown metal sample is B. Mass = 198.0 g, Volume = 24.0 cm³.

To calculate density, we use the formula: Density = Mass/Volume. In this case, the mass is 198.0 g and the volume is 24.0 cm³. Dividing the mass by the volume gives us a density of 8.25 g/cm³, which matches the calculated value provided by the student.
