How many moles are in CH3CH2OH?

Answer and Explanation:

There are 0.087 moles of ethanol, CH3CH2OH, in a 4.00-gram sample of ethanol. The molar mass of the ethanol molecule is 46.07 grams per mole.

How many grams are in 1 mole of ethanol?

The molecular mass of a molecule is measured in g/mol. In this case, ethanol’s molecular mass is 46 g/mol. This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably. The same is true of a mole.

How many moles are in 50 g of water?

1 Answer. There are 3 moles of O in 50 g.

How do you calculate moles of ethanol?

  1. Ethanol 46 g/mol.
  2. Water 18 g/mol.
  3. Calculate moles of ethanol: 14.6 grams x 1 mol / 46 grams = 0.317 moles.
  4. Calculate moles of water: 53.6 grams x 1 mol / 18 grams = 2.98 moles.
  5. Mole fraction = moles of component / total moles in solution.
  6. = 0.317 / (0.317 + 2.98) = 0.0963.
  7. Sulfuric acid 101 g/mol.
