Question

ead use ofT biodlesel fuel using this synthetic method. Prelab 1 Caicuiate the molar mass of potassium hydroxide, KOH 2. Approximately 5.9 g of KOH is needed to catalyze the transesterification process for 1L of oil to biodiesel. Calculate the mass of KOH needed to convert 100 mL of oil to biodiesei. 3. Convert the mass of KOH determined in (2) above to moles. 4. What volume of methanol needs to be added to this many moles of KOH to produce a 0.4 M solution of potassium methoxide (CH3O K*)? NOTE: During the lab practical session, you will be provided with a 0.4 M solution of potassium methoxide (you don't have to prepare it yourself), but you will know how much (mL) to add to the reaction vessel for the reaction to proceed (see step #4 in lab procedure). 5. What are the densities of glycerol and biodiesel? If glycerol and biodiesel were poured into a flask, which one would be the top phase? 6. Locate a Safety Data Sheet for methanol and potassium hydroxide. List the specific hazards and cautions associated with using these two chemicals. Complete items 1-6 and hand in a copy to your TA at the start of your lab session
