Can anyone help me with this question on mass spectrometry.. I'm a bit stuck... 
State how the relative molecular mass of a covalent compound is obtained from it's mass spectrum.

If you are a 'bit' stuck on this question I suggest you read up on the absolute basics of mass spectrometry

I know its veery basic ... I just dont get the covalent compounds bit... do you just add up the relative atomic masses of each of the atoms in the molecule... (as I guess the molecule is split up due to losing the electron(s) that keep them together)...????

Covalent (organic) compounds can get fragmented in a mass spec. In A2 you will learn how to use these fragments to identify compounds.
The mass spec gives info on m/z ratio and abundance. For an organic compound the peak with the highest m/z ratio is equivalent to the RMM of the compound as it has the mass of the unfragmented molecule. It's called the molecular ion.
