Elemental $\mathrm{S}$ reacts with ${\mathrm{O}}_2$ to form ${\mathrm{SO}}_3$ according to the reaction $2\mathrm{S}+3{\mathrm{O}}_2?2{\mathrm{SO}}_3$ as depicted here.(Figure 1) How many ${\mathrm{O}}_2$ molecules are needed to react with $5.93\mathrm{g}$ of $\mathrm{S}$ ? Express your answer numerically in units of molecules. Part B What is the theoretical yield of ${\mathrm{SO}}_3$ produced by $5.93\mathrm{g}$ of $\mathrm{S}$ ? Express your answer numerically in grams. ? Limiting reactant Next, consider a situation in which all of the $\mathrm{S}$ is consumed before all of the ${\mathrm{O}}_2$ reacts, or one in which you have excess $\mathrm{S}$ because all of the ${\mathrm{O}}_2$ has been used up.
