Oxygen consists of isotopes `O^(16),O^(17)` and `O^(16)` and carbon consists of isotopes `C^(12)` and `C^(13)` .How many types of `CO_(2)` molecules can be formed ? Also repart their molecular weights

Explanation

To determine how many types of CO₂ molecules can be formed from the isotopes of oxygen and carbon, we can follow these steps:

### Step 1: Identify the Isotopes
- **Oxygen Isotopes**: O-16, O-17, O-18
- **Carbon Isotopes**: C-12, C-13

### Step 2: Determine Combinations for Each Carbon Isotope
1. **For Carbon-12 (C-12)**:
