Calculate the total positive (or negative) charge on a 3.11 g copper penny. Given Avogadro's number `=6.023xx10^(23)(g^(-1)) mol^(-1),`, Given Avogadro's number and atomic mass=63.5.

Explanation

To calculate the total positive (or negative) charge on a 3.11 g copper penny, we will follow these steps:

### Step 1: Calculate the number of moles of copper in the penny
To find the number of moles, we use the formula:
\[ \text{Number of moles} = \frac{\text{mass (g)}}{\text{atomic mass (g/mol)}} \]
Given:
...
