how many hydrogen atoms are contained in one mole of ethanol?
529358
Because 1 mol of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol.

We assume you are converting between moles Ethanol and gram. You can view more details on each measurement unit: molecular weight of Ethanol or grams The molecular formula for Ethanol is CH3CH2OH. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Ethanol, or 46.06844 grams.
