Question

Answer the following questions about the conversion of the sucrose (C12H,2011) in sugarcane to ethanol (CHO) and Co, according to the following unbalanced equation. This conversion allows for sugarcane to be used as a renewable source of ethanol, a fuel additive in gasoline. C12H220n() + H2O(l) → C2H6O() + CO2 sucrose ethanol w. What is the molar mass of sucrose? mol b. Balance the given equation. c. How many moles of ethanol are formed from 2 mol of sucrose? molethanol d. How many moles of water are needed to react with 17 mol of sucrose? mol water e. How many grams of ethanol are formed from 0.0 mol of sucrose? Bethanol Illow many grams of ethanol are formed from 53.9 g of sucrose? Bethanol What is the theoretical vield of ethanol in grams from 18.2 of sucrose? Bethanol h. IT 3.25 of ethanol are formed in the reaction in part(s), what is the percent Vield of ethanol
