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

Explanation

To solve the problem, we need to calculate the number of ions, the number of oxygen atoms, and the total charge in 3 grams of \( \text{CO}_3^{2-} \).

### Step 1: Calculate the moles of \( \text{CO}_3^{2-} \)

1. **Determine the molar mass of \( \text{CO}_3^{2-} \)**:
- Atomic mass of Carbon (C) = 12 g/mol
- Atomic mass of Oxygen (O) = 16 g/mol
- Molar mass of \( \text{CO}_3^{2-} = 12 + (3 \times 16) = 12 + 48 = 60 \) g/mol
