Atomic Structure (2.1.1) Flashcards
1
Q
What is the relative atomic mas
A
the weighted mean mass of an atom compared with 1/12th mass of an atom of carbon-12
2
Q
How do you calculate the relative atomic mass, using data from a mass spectrometer using percentage abundances
A
sum of (isotopic mass x %abundance) / 100
3
Q
When rearranging Ar calculations if you think of abundance in terms of percent?
A
x + y = 100
3
Q
How do you calculate the relative atomic mass, using data from a mass spectrometer using numerical abundances
A
sum of (isotopic mass x relative abundance) / total relative abundance
4
Q
When rearranging Ar calculations if you think of abundance in terms of number?
A
x + y = 1
