## How many moles are in 100g of ethanol?

**2.173 moles** of ethanol are present in a 100.0 g sample of ethanol. Explanation: The ‘amount of substance’ that contains as ‘many particles’ as there are atoms in exactly ’12 g of Carbon’- 12 isotope is called one mole.

## How do you calculate grams to moles?

**Divide the mass of the substance in grams by its molecular weight**. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
