...according to the following equation:
2NH3 + H2 SO4 yields (NH4)2 SO4 ?
I'm having a hard time with moles. :(

Notice that it takes 2 mols of NH3 to make one mole of ammonium sulfate. Then 30 moles of NH3 will make 15 mols of ammonium sulfate.

Moles are easy, really. You have a number given to you in the problem and it's asking how many moles of Ammonium Sulfate.
You have to switch substances. This is the cancellation method.
?Moles (NH4)2SO4 = (1 mole (NH4)2SO4 / 2 moles NH3) X ( 30.0 moles NH3 / *Place holder or "1"*) There you go.
For more practice, I'll be updating this right off and adding more problems. Currently I have three :P http://www.sciencewoods.com/basiccancellation.html

use the equation to get a mole ratio
2NH3 + H2SO4 yields (NH4)2SO4
2 : 1 : 1 This is the mole ratio.
So if there are 30 moles of NH3 then half the amount of (NH4)2SO4 would be produced which is 15 moles.

from the equation 3moles of H2 will produce 2 moles of NH3 for this reason 9.5 moles of H2 will produce x molesf NH3 (x/9.5) = (2/3) x = (2/3)9.5 = 19/3 = 6.333 for this reason 9.5 moles of H2 will react to form 6.3 moles of NH3.
