Options:
A) kg/m³
B) g/cm³
C) mol/L
D) cm/s²

Answer 1

The density of mobile electrons in copper metal is 8.4 x 10²⁸ electrons per cubic meter.

Step-by-step explanation:

The density of mobile electrons in copper metal is 8.4 x 10²⁸ electrons per cubic meter. This means that in one cubic meter of copper, there are 8.4 x 10²⁸ free electrons.
