Fermentation is a complex chemical process of making wine by converting glucose C6H12O6 into ethanol C2H5OH and carbon dioxide: C6H12O6(s) ---> 2 C2H5OH (l) + 2 CO2(g) Calculate the mass of ethanol produced if 500.0 grams of glucose reacts completely.

Explanation:

First, we have to check if the reaction is balanced:

We have 6 carbon atoms on both sides, 12 hydrogens, and 6 oxygens. So, we can continue with the problem. If we want to calculate the mass of ethanol () we need to know:

1) Molar mass of glucose ()

In this case, we have to know the atomic mass of each atom:

-) C 12 g/mol

-) O 16 g/mol

-) H 1 g/mol

With the formula we can calculate the molar mass:

(12*6) + (16*6) + (1*12) = 180 g/mol

2) Molar ratio between glucose and ethanol

In the balanced equation we have 1 mol of and 2 moles of . So the molar mass is 1:2

3) Molar mass of ethanol ()

With the formula, we can calculate the molar mass:

(12*2) + (6*1) + (16*1) = 46 g/mol

Finally, we can to the calculation:
