The relative abundance of ""^(12)C and "...

The relative abundance of `""^(12)C and ""^(13)C` are respectively 98.892 and 1.108. If the atomic masses of `""^(12)C and ""^(13)C` are 12 u and 13.0035 u, respectively, calculate the ave rage atomic mass of carbon.

Text Solution

Verified by Experts

Average atomic mass of carbon = `((98.892xx12)xx(1.108xx13.00335))/((98.892+1.108))=12.011u`
