How many electrons are in a cubic inch of copper? - Answers

Given:1 cubic inch = 16.387064 cubic centimeters.Density of copper at STP = 8.94 g/cm^3.Copper has 29 electrons per atom.GMW Cu: 63.546 g/molNA: 6.02 x 10^23Calculate:One cubic inch of copper converted to cubic centimeters: 16.387064 cm^316.387064 cm^3 * 8.94 grams/cm^3 = 146.50035216 gramsMoles of copper in 146.50035216 grams: 2.30542 molAtoms in 2.30542 moles: 1.38786284 x 10^24Electrons in 1.38786284 x 10^24 moles: 4.024802236 x 10^25Note: The precision of the answer is driven by the three significant digits in the density value and the approximation of Avogadro's number.Round to 3 significant digits: 4.02 x10^25 electrons is your final answer.
