2. Silicon has three stable isotopes, 28Si (27.9769 amu), 29Si (28.9764 amu), and 30Si (29.9737
amu). The ratio of the abundance of 29Si to the abundance of 30Si is 1.517. If all the 30Si atoms in
a naturally occurring sample were replaced by engineered ³¹Si (30.9726 amu), what would the
average atomic mass be?
