What Is the Molar Mass of C2H5OH?

The molar mass of C2H5OH, commonly known as ethanol, is 46.07 grams per mole. The molecular formula of ethanol is CH3CH2OH, which reflects how the hydrogen atoms link up with each carbon atom.

Ethanol is the metabolic by-product of yeast, which humans have used for thousands of years in creating alcoholic beverages. In addition to consumption, ethanol can be used as a solvent, a fuel and as an antiseptic. As a fuel, it is usually used as an additive instead of being a vehicle's primary fuel source. Brazil is the global leader of ethanol fuel use, with a 25 percent additive rate. Around 90 percent of new cars sold in Brazil run on ethanol.
