Nitrogen gas reacts with hydrogen gas to produce ammonia.
N2(g)+3H2(g)→2NH3(g)
How many grams of NH3 can be produced from 10.4 g of H2?
Express your answer with the appropriate units.
Solution: ν(H2)=10.4/2=5.2 mol 3 mol H2→2 mol NH3, so ν(NH3)=(5.2/3)*2=3.47 mol m(NH3)=17*3.47-=58.99 g Answer: 58.99 grams of NH3.

How many grams of sodium hydroxide would you need to produce 75 g of lead (II) hydroxide? 2 NaOH(aq) + Pb(NO3)2(aq) → 2 NaNO3(aq) + Pb(OH)2(s)
n(Pb(OH)2) = m/M = 75 g/241.21 g/mol = 0.31 molm(NaOH) = n*M = 2*n(Pb(OH)2)*M(NaOH) = 24.8 g
