Answer: Volume = 0.01L
Explanation:
The density of a substance is given by; Density = Mass / Volume.
In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L
For the units to be uniform, we convert 1000g to Kg = 1Kg
Therefore, Volume = Mass / Density = 1Kg / 100Kg/L = 0.01L
Option d: copper.
Because copper is an element, not a mixture.
