(a)
Interpretation:
Glucose and sucrose undergo combustion with oxygen and produce carbon dioxide and water.
Number of moles of oxygen required per mole of each sugar for the reaction completion has to be calculated.
(b)
Interpretation:
Number of grams of oxygen required per mole of each sugar for the reaction completion has to be calculated.
Concept introduction:
Molar mass of a substance is the mass in grams of one mole of a substance.
(c)
Interpretation:
From the given combustion reaction, the formation of more water per gram sugar has to be identified. Number of grams of water produced per gram of each sugar for the reaction has to be calculated.

- Ethanol, C2H5OH, is a gasoline additive that can be produced by fermentation of glucose. C6H12O62C2H5OH+2CO2 (a) Calculate the mass (g) of ethanol produced by the fermentation of 1.000 lb glucose. (b) Gasohol is a mixture of 10.00 mL ethanol per 90.00 mL gasoline. Calculate the mass (in g) of glucose required to produce the ethanol in 1.00 gal gasohol. Density of ethanol = 0.785 g/mL. (c) By 2022, the U. S. Energy Independence and Security Act calls for annual production of 3.6 1010 gal of ethanol, no more than 40% of it produced by fermentation of corn. Fermentation of 1 ton (2.2 103 lb) of corn yields approximately 106 gal of ethanol. The average corn yield in the United States is about 2.1 105 lb per 1.0 105 m2. Calculate the acreage (in m2) required to raise corn solely for ethanol production in 2022 in the United States.arrow_forwardA newspaper article states that biomass has actually been used as an energy source throughout human history.

- The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.arrow_forwardConsider the following balanced chemical reaction which occurs during glycolysis. 2 C6H12O6 + 2 Na3PO4 → 2 C6H12O5PO2 + 3 Na2O2 a) If 25.5 mole of glucose (C6H12O6) reacts, then how many mole of sodium peroxide (Na2O2) are produced? b) What is the molar mass of glucose (C6H12O6)?

HFCS 55 is the type found in US sodas (like Coca Cola) and it contains 55.1% fructose molecules and 44.9% glucose molecules. Given that information, calculate how many molecules of fructose would be found in a can of coca cola if the amount of HFCS used were 67.5 g?
