Question

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

Answer 1

Total number of molecules of `CO_(2) = 12`
bb "Types of molecules" bb "Molecular weight"
1. `C^(12)O^(16)O^(16)` `44`
2. `C^(12)O^(17)O^(17)` `40`
3. `C^(12)0^(16)O^(18)` `48`
4. `C^(12)O^(16)0^(17)` `45`
5. `C^(12)O^(16)0^(18)` `46`
6. `C^(12)0^(17)0^(18)` `47`
Similarly six molecules with `C^(13)` isotope can be found
