Hey kiddo. 
You asked this three times now.
Don't panic over it. These questions are rarely asked, and they're not difficult because you get them in these packages:
Package A: Total mass of compound, identities of elements which make up the compound, and hence the molar masses of these elements.
Package B: This is working out the empirical formula - percentage composition of elements in the compound, and identities of the compound.
For A, it's a simple matter of trial and error. I have never had to do one of those for any of my exams, so worry not. For B, I have already given you the link to a relevant thread, but here it is again: http://community.boredofstudies.org/showthread.php?t=84658.
