Each mole of glycerol tristearate produces 3 mol of sodium stearate. The balanced equation is: (glycerol tristearate) + 3NaOH → 3(sodium stearate) + Glycerol The required mole ratio is: 3 mol sodium stearate1 mol glycerol tristearate#1: Amount of glycerol tristearate used = 0.182 g Molar mass of glycerol tristearate = 891.50 g/mol => moles of glycerol tristearate used = 0.182 g x 1 mol891.50 g = 2.04x10-4 mol moles of glycerol tristearate used = 2.04x10-4 mol (Answer) #2: Amount of soap, sodium stearate produced = 0.317 g Molar mass of sodium stearate = 306.46 g/mol => moles of sodium stearate produced = 0.317 g x 1 mol306.46 g = 1.03x10-3 mol moles of sodium stearate produced = 1.03x10-3 mol (Answer)#3: moles of glycerol tristearate used = 2.04x10-4 mol Theoretical yield of sodium stearate = 2.04x10-4 glycerol tristearate x 3 mol sodium stearate1 mol glycerol tristearate= 6.12x10-4 mol sodium stearate Theoretical yield of sodium stearate = 6.12x10-4 mol (Answer) = 6.12x10-4 mol x 306.46 g1 mol= 0.188 g Theoretical yield of sodium stearate = 0.188 g (Answer) #4: Percent yield = Actual yield of sodium stearateTheoretical yield of sodium stearatex100= 0.317 g0.188 gx100= 169% (Answer)
