WebWhen bromine water is added to a colorless solution of acetone in water, the solution turns the characteristic yellowish-orange color of elemental bromine. But the color disappears … WebFirst, we need to calculate the number of moles of trans-cinnamic acid used in the reaction: 0.5 g / 148.16 g/mol = 0.00337 mol. Since the stoichiometry of the reaction shows that 1 mol of trans-cinnamic acid reacts with 1 mol of 2,3-dibromo-3-phenylpropanoic acid, the theoretical yield of the product is: 0.00337 mol × 365.04 g/mol = 1.23 g
