The amount of any substrate containing as many elementary particles add there are carbon atoms in exactly 12 grams of carbon 12 Avagadros number 6.0221415x10^23
Moles=Mass÷Mr |

|
Molecular formula |
A formula that shows the number and type of aims of each element present in a molecule Mr |
|
|
Empirical formula |
The formula that shows the simplest whole number ratio of atoms of each element present in a compound % by mass÷Ar for each element ÷ the radio by the smallest number throughout Apply each part of the ratio to each atom Multiply until it becomes whole number ratio |
|
|
Isotopes |
Atoms of the same element with different numbers of neutrons and therefore different masses |
|
|
Converting empirical formula to molecular formula |
Empirical mass (Ar+Ar+Ar etc) Divide Mr by empirical mass Multiply up each of the atoms by Mr ÷ empirical mass |
