Using the molar mass of nh3, we find that we have 2.5 moles of nh3. Since 3 moles of h2o are produced per 2 moles of nh3, we see that we will produce 3.75 moles of h2o. This is equivalent to around 3.79 g.

∙ 6y ago4NH3 + 5O2 ==> 4NO + 6H2O balanced equation for the reaction4.5 moles NH3/4 = 1.125
3.2 moles O2/5 = 0.64 THIS IS THE LIMITING REACTANT
moles of H2O formed = 3.2 moles O2 x 6 moles H2O/5 moles O2 = 3.84 moles H2O formed

∙ 9y ago42.5 g of NH3 is equivalent to around 2.5 moles. Since there are 3 moles of H2O produced for every 2 moles of NH3 used, 3.75 moles of H2O are produced. This around 3.79 g of water.
