We cannot calculate this on the given data...

Explanation:

The #"average atomic mass"#, i.e. the mass quoted on the Periodic Table, is the WEIGHTED average of the individual isotopic masses. We KNOW that the average atomic mass is #28.1*"amu"#...we DO NOT know the individual percentages of #""^28Si#, #""^29Si#, and #""^30Si#. More data are needed for the question...
