Solution Preview

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 ...

Solution Summary

The solution calculates the mass in grams of alcohol produced.
