Equations Flashcards
1
Q
What is charge density?
A
charge density = charge / size
2
Q
What is relative atomic mass?
A
RAM = (mass x abundance) + (mass x abundance) / total abundance
3
Q
What is kinetic energy?
A
KE = (mv^2) / 2
4
Q
What is velocity?
A
v = d/t
5
Q
What is the mass of one ion?
A
mass of one ion (in g) = relative isotopic mass / 6.022 x 10^23
6
Q
What is the velocity calculation?
A
Va = root (mb x Vb^2) / ma
7
Q
What is the time of flight calculation?
A
ta = root (tb^2 x ma) / mb
8
Q
How do you show the time of flight using the kinetic energy equation?
A
t=d x root(m/2KE)
