Mathematics

10.8109 amu

Step-by-step explanation:

The average atomic mass of boron is determined as the average of the atomic masses of both isotopes weighed by their respective abundances.

Therefore, the average atomic mass is given by:

$M=10.0129*0.1991+11.0093*0.8009\\M=10.8109\ amu$

The average atomic mass of boron isotopes is 10.8109 amu.
