You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula.

What are the units of molarity? The units of molarity are M or mol/L. A 1 M solution is said to be “one molar”. Two solutions that have the same molarity will have the same number of molecules of the ...

The gram formula mass (GFM) of a substance is known as the mass of one mole. Relative atomic masses of selected elements can be found in the SQA Data Booklet.These can be used to calculate the ...
