C6H12O6 (aq) -> 2 C2H5OH (aq) + 2 CO2 (g) a. How many moles of CO2 are produced when 0.400 mol of C6H12O6 reacts in this
fashion?
b. How many grams of C6H12O6 are needed to form 7.50 g of C2H5OH?
c. How many grams of CO2 form when 7.50 g of C2H5OH are produced?

a. 0.8 moles of CO₂ are produced when 0.400 mol of C₆H₁₂O₆ reacts.

b. 7.5 grams of C₂H₅OH are produced by 14.67 grams of C₆H₁₂O₆.

c. 7.17 grams of CO₂ form when 7.50 g of C₂H₅OH are produced.

Explanation:

The balanced reaction is:

C₆H₁₂O₆  → 2 C₂H₅OH + 2 CO₂

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

The molar mass of each compound is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Then you can apply the following rules of three:

a. If 1 mole of C₆H₁₂O₆ produces 2 moles of CO₂, 0.4 moles of C₆H₁₂O₆ produces how many moles of CO₂?

moles of CO₂= 0.8 moles

0.8 moles of CO₂ are produced when 0.400 mol of C₆H₁₂O₆ reacts.

b. If 92 grams of C₂H₅OH are produced by 180 grams of C₆H₁₂O₆, 7.5 grams of C₂H₅OH are produced by how many mass of C₆H₁₂O₆?

mass of C₆H₁₂O₆= 14.67 grams

7.5 grams of C₂H₅OH are produced by 14.67 grams of C₆H₁₂O₆.

c. If 92 grams of C₂H₅OH are produced along with 88 grams of CO₂, 7.5 grams of C₂H₅OH are produced along with how many mass of CO₂?

mass of CO₂= 7.17 grams

7.17 grams of CO₂ form when 7.50 g of C₂H₅OH are produced.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
