Chem- 1.2

What is relative molecular mass?

The average mass of a molecule on a scale where an atom of carbon 12 is 12.

What is Empirical Formula?

'The lowest whole number ratio of all atoms in a molecule' OR 'the smallest molecular formulae of this compound'

What is relative atomic mass?

The average mass of an element compared to the one-twelfth of the mass of a single carbon-12 atom

State what is meant by the term one mole of molecules

Avogadro's constant

How do you show Avogadro's constant

(mass of one mol of a molecule)/(mass of one atom of that molecule)

How to work out concentration?

mole/volume

Name the moles, mass mr equation
