Calculate the number of ions, number of oxygen atom and total charge in 3 gm `CO_(3)^(2-)`

Explanation

To solve the problem step by step, we will calculate the number of ions, the number of oxygen atoms, and the total charge in 3 grams of the carbonate ion \((CO_3)^{2-}\).

### Step 1: Calculate the molar mass of the carbonate ion \((CO_3)^{2-}\)

The molar mass of the carbonate ion can be calculated as follows:
- Carbon (C) has a molar mass of approximately 12 g/mol.
- Oxygen (O) has a molar mass of approximately 16 g/mol.
- The carbonate ion has 1 carbon atom and 3 oxygen atoms.
