## How many moles are there in 3.00 g of ethanol CH3CH2OH?

Answer and Explanation:

There are 0.065 moles in a 3.00-gram sample of ethanol, CH3 CH2 OH. The molar mass of ethanol with this chemical formula is 46.07 grams.

## 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 of ethanol are present in the sample?

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 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?

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

## Is Avogadro’s Number?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant.

## How many moles are in 5 mg of aspartame?

Answer and Explanation: Mass of aspartame = 5 mg = 0.005 grams. Also, molar mass of aspartame = 294.3 grams. Now, moles of aspartame = {eq}frac{mass}{molar Mass of aspartame = 5 mg = 0.005 grams.

…
