I have 1.189 g H2O

I converted this to mols

1.189g   (1 mol/18g)    =    .06605 mols H2O

How many moles of H are in the 0.06605 mols H2O?

There should be .1321 mol H because of the 2H correct?

So there is 0.1321 mol H in H2O   
or
there is 0.1321 mol H₂ in H2O       This is causing me a problem (see below)

When I calculate grams of H from the mol of H (or H₂?): 

.1321 mol H (1.008 g H/ 1 mol H) = .1331 g H

or should it of been

.1321 mol H₂  (2.016 g H₂ / 1 mol H₂)

??

OK

or
there is 0.1321 mol H₂ in H2O

No, when it is H₂, there is half of the above - so .06605 moles of H₂.
