Answer:
1402.73 m
Explanation:
Mass of Azurite=3.25 lb
Percent of copper in AZurite mineral=55.1%
Diameter of copper wire,d=0.0113 in
Radius of copper wire=

Density of copper=
1 lb=454 g
3.25 lb=
Mass of Azurite=
Mass of copper=
Density=
Using the formula

Volume of copper wire=
Radius of copper wire=
1 in=2.54 cm
Volume of copper wire=

Using the formula



1 m=100 cm

Hence, the length of copper wire required=1402.73 m
