The theoretical yield of 1,2-epoxycyclohexane is _grams, when starting with 3.0 grams of trans-2- bromocyclohexanol. (Enter the number using 3 significant figures, i.e. 1.22) Given: 3.0 g of trans-2-bromocyclohexanol FW: 179.05 25 mL of 10% NaOH FW: 40 and density: 1.11 g/mL 1,2-expoxycyclohexane FW: 98.15 Hint: Identify the limiting reactant (NaOH or trans-2- bromocyclohexanol) by calculating the number of moles of each. For 1 mole of limiting reactant, 1 mole of product is formed. Use the # of moles and...
