Answer 1

Answer #1

The reaction you are talking about must be

N2 + 3H2 --> 2NH3

So as per stoichiometry of above reaction , 2 moles of NH3 will be produced by 3 moles of H2

the moles of H2 used here = Mass of H2 / Molecular weight of H2 = 3.06 X 10^-4 / 2 = 1.53 X 10^-4 moles

so moles of NH3 produced will be = 2 X 1.53 X 10^-4 moles / 3 = 1.02 X 10^-4 moles

Molecules of NH3 produced = moles X avagadro number of molecules = 1.02 X 10^-4 X 6.023 X 10^23 molecules

Molecules of NH3 = 6.143 X 10^19 molecules

Learning Goal: To understand how to use stoichiometry to convert between quantities of reactants and products in chemical equations. Stoichiometry describes the quantitative relationships among the reactants and products of a balanced reaction by directly comparing mole ratios. Stoichiometry can be used to convert mass, number of moles, or number of particles between products and reactants, as shown in the flowchart displayed in the figure. (Figure 1)How many grams of NH3 can be produced from 4.74 mol of N2 and excess H2. Express...
