Equations

Question 1

What is charge density?

Answer 1

charge density = charge / size

Question 2

What is relative atomic mass?

Answer 2

RAM = (mass x abundance) + (mass x abundance) / total abundance

Question 3

What is kinetic energy?

Answer 3

KE = (mv^2) / 2

Question 4

What is velocity?

Answer 4

v = d/t

Question 5

What is the mass of one ion?

Answer 5

mass of one ion (in g) = relative isotopic mass / 6.022 x 10^23

Question 6

What is the velocity calculation?

Answer 6

Va = root (mb x Vb^2) / ma

Question 7

What is the time of flight calculation?

Answer 7

ta = root (tb^2 x ma) / mb

Question 8

How do you show the time of flight using the kinetic energy equation?

Answer 8

t=d x root(m/2KE)
