(optional) A 1980 penny weighing 3,079 g reacts with nitric acid to give a blue solution. An ectric current is passed through the solution and 2.925 g of copper metal is produced. What is the percentage of copper in the 1980 penny?Explanation / Answer
total weight of penny = 3.079gm
the weight of copper metal =2.925gm
percentage of copper metal in penny = (weight of copper metal / total weight of the penny) *100
percentage of copper metal in penny = (2.925/3.079)*100
percentage of copper metal in penny = 94.9983761%
