How many grams of NH3 can be produced from 4.74 mol of N2 and excess H2.
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...
