The relative abundance of three isotopes of carbon `C^(12), C^(13)` and `C^14` are 98.892%, 1.108% and `2 xx 10^(-10)`% respectively. If the relative atomic masses of these isotopes are 12.00, 13.00335 and 14.00317 amu respectively, find the average atomic mass of carbon.

Explanation

To find the average atomic mass of carbon based on the relative abundances and atomic masses of its isotopes, we can follow these steps:

### Step 1: Write down the data
We have three isotopes of carbon with the following relative abundances and atomic masses:
- Isotope \( C^{12} \):
- Relative abundance = 98.892%
- Atomic mass = 12.00 amu
- Isotope \( C^{13} \):
