These are all the equations that you need to know for CH1:

relative atomic mass = (abundance % x m/z)(abundance % x m/z) / 100

different isotopes

Empirical formula:

  • Molar ratio of atoms / mass number
  • then divide by smallest number

Molecular formula:

  • molar mass / sum of empirical formula

For solid:

number of moles = mass of substance / molar mass

For solution:

number of moles = concentration x volume

For gas:

number of moles = volume of gas / molar volume

at 0 degress molar…
