this is confusing me so bad!!
Nitrogen gas reacts with hydrogen gas to produce ammonia by the following equation:
N2(g)+3H2(g)→2NH3(g)
If you have 5.79g of H2, how many grams of NH3 can be produced?
I said, 2/3 *5.79 = 3.86 but that's not the answer.. it says the answer is 32.5 g? how??

How many grams of H2 are needed to react with 2.30 g N2? Do I need to find moles or something?? I was trying to mole ratio then times the mass of element?

nevermind, I figured it out... ughhhhh

You're still trying to make grams go to grams. You CAN'T do that. You MUST change grams to mols, convert mols of what you have to mols of what you want, then change back to grams.
