analytical technique

Question 1

what is Mass spectrometry?

Answer 1

Mass spectrometry is a technique that can be used to determine the specific identity and amount of atoms or molecules in a sample of material. In particular it can determine the isotopic composition of an element.

Question 2

dont need

Answer 2

press perfect

Question 3

what is absorption spectrometry?

Answer 3

uses the unique energy emitted by atoms to determine the elements

Question 4

is it true that as the electron gains energy and drops a electron shell?

Answer 4

false

Question 5

what is atomic absorption spectroscopy?

Answer 5

Atomic absorption spectroscopy (AAS) is a modified version of absorption spectroscopy that can also be used to perform qualitative analysis to find the amount of an element present.

Question 6

what is the formula to calculate the relative atomic mass?

Answer 6

(relative isotope mass x %abundance)/100

Question 7

what is the formula to solve an unknown relative atomic mass with the a graph with relative abundance % and m/z

Answer 7

((mass x %abundance) for all lines )/100
