A copper wire (density = 8.96 g/cm3) has a diameter of 0.19 mm. If a sample of this copper wire has a mass of 48 g, how long is the wire?
Perform the following mathematical operations, and express each result to the correct number of significant figures.
0.19*6.022*10^23
(4.0*10^4)*(5.170*10^-3)*(7.34993*10^2)
6.0*10^6/3.00*10^-7
