Post-Lab Questions Wrile your ansvers in pen and include units 1. The following chemical equation has been balanced for you (at wt, N = 1401 H-1.008) N2 + 3H2 2NH3 What is the molecular weight of N2 (Note: two N's) What is the molecular weight of H (Note: two H's) What is the molecular weight of NH 2. What mass, in grams, of NH, can be produced from 50.0 g of N? Show your work below -g/mol g/mol g/mol 3. What mass, in grams, of NH, can be produced from 20.0 g of H? Show your work below: 4. What mass, in grams, of NH, can be produced from 50.0 g of N2 and 20.0 g H2? That is, what is the limiting reactant and the theoretical yield? (Combine answers from "2 and), 91Explanation / Answer
1) 28.02 g/mol N2
2.016 g/mol for one H2 6.048 g/mol for 3H2
17.034 g/mol for 1 NH3 34.068 g/mol for 2NH3
2) 28.02 g N2 produces 34.068 g NH3
50 g N2 produces x g NH3
x=50x34.068/28.02
60.79 g NH3 produced
3) 6.048 g H2 produces 34.068 g NH3
20 g H2 produces x g NH3
x=20*34.068/6.048
112.66 g NH3 will produce
4) N2 is limiting reagent so all N2 will utilize 60.79 g NH3 will produce.
