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...
