1 mesa-stilbene dibromide + 2 KOH --------> 1 Diphenylacetylene + 2 H2O + 2 KBr The reaction is run on 0.0015 mole of meso-stilbene dibromide. Calculate how many grams are needed. A 50% molar excess of KOH over the stoichiometrically required amount is used. KOH pellets (~85% KOH content) typically weigh about 0.1 g and are not easily divided. Because a considerable excess is used, the precise mass is not critical. Determine the number of pellets required to give roughly...

Use the following atomic weights and quantities to calculate the overall % yield of diphenylacetylene. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent. Filling out most of the chart will help. Give...
