(Answered) When a sample is vaporized and injected into a mass

Academics

When a sample is vaporized and injected into a mass spectrometer, the following results are obtained.

Mass of Atom (amu)	% Abundance
143.911995	3.07
146.914893	14.99
147.914818	11.24
148.917180	13.82
149.917271	7.38
151.919728	26.75
153.922205	22.75

Calculate the atomic mass using the weighted average mass method and identify the element. Write a 2-to-3-page report discussing the data and the calculations performed.
