An unknown element has three stable isotopes with average atomic
masses of 27.53 amu (45.80%), 30.00 amu (33.50%), and 32.59 amu
(20.7%). The natural abundance of each is given in the parentheses
above. What is the average atomic mass of the unknown element with
the correct number of significant figures?
