Enzymes in yeast convert sugar (C6H12O6) to alcohol (C2H5OH) according to the following equation:
C6H12O6 2 C2H5OH + 2 CO2
If you start with 270 grams of sugar, how many grams of alcohol will be produced?
If we have 270 grams of sugar (C6H12O6), the first thing we need to find is the molecular weight and the number of moles of sugar.
Molecular Weight, MW = 6 (MW Carbon) + 12 (MW Hydrogen) + 6 (MW Oxygen)
= 6 (12.01 g/mol) + 12 (1.01 g/mol) + 6 (16.00 g/mol)
= 180.18 ...
The solution calculates the mass in grams of alcohol produced.
