Question

Daniel has a sample of pure copper. Its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). What’s the density of the sample?
0.11 g/cm3
8.96 g/cm3
11.1 g/cm3
896 g/cm3

Answer 1

Answer: 8.96 g/cm3

Explanation: Density is defined as the mass of a substance contained in unit volume of a substance.

$Density=\frac{mass}{volume}$

Given : mass of pure copper = 89.6 g

Volume of copper= $cm^3$

thus $Density=\frac{89.6g}{10cm^3}$

$\text {Density of the sample of copper is}}=8.96g/cm^3$

Answer 2

Density = mass /volume = 89.6/10 = 8.96gm/cm^3.
