Pennies today are copper-covered zinc, but older pennies are 3.1 g of solid copper. What is the total positive charge in megacoloumbs (106 C) in a solid copper penny that is electrically neutral? The density of copper is 8900 kg/m^3.

total positive charge in one copper penny is 0.3 MC

Explanation:

As we know that the atomic number of copper is

z = 29

now moles of copper present in one copper penny is given as

now total number of copper atoms present in it

Now we know that in one atom there exist 29 protons and 29 electrons

so total positive charge in it

are there options? cause you ain’t. real specific

the answer is 3.1 his answer is wrong mines is right
