Calculate the cost of ingredients to make one gallon of biodiesel from waste vegetable oil (WVO). Assume that all of the waste oil is converted to fatty acid methyl esters and that 1 gallon of WVO yields 1 gallon of FAME. Scale up the reaction from a 10 mL sample of WVO, 2 mL of methanol and 0.1 g DRANO. Calculate the cost of the reactants to convert one gallon of WVO into one gallon of biofuel.
