What is needed to calculate the mass of ammonia gas produced from 2.0 L of nitrogen gas in excess hydrogen gas in the reaction below?
N2(g) + 3H2(g) ® 2NH3(g)?
Nothing but the coefficients in the balanced equation and convert to grams.
2.0 L N2 x (2 moles NH3/1 mole N2) = L NH3.
Convert L NH3 to moles (there are 22.4 L in a mole), then g = moles x molar mass.
