Question

A piece of copper has a volume 130 L. What is the mass of the sample, in units of kilograms?

Answer 1

Answer: The mass of the sample is 1264.800 kg.

Explanation:

Mass of the piece of copper = m

Volume of the copper price = $130 L=130,000 cm^3$

$1 L= 1,000 cm^3$

$Density=8.96 g/cm^3=\frac{Mass}{Volume}=\frac{Mass}{130,000 cm^3}$

$m=Density\times Volume=8.96 g/cm^3\times 130,000=1,264,800 g$

m = 1,264,800 g = 1,264.800 kg (1 kg = 1000 g)

The mass of the sample is 1264.800 kg.
