Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s const
To calculate the number of atoms and molecules present in a water droplet, you need to know the chemical formula of water. There is one atom of oxygen, and two atoms of hydrogen in each water molecule, each molecule of water contains three atoms, making the formula H2O. Molar Mass of Wa...

To solve the question, we will break it down into two parts: Part (i): Calculate the number of atoms in 0.25 moles of carbon.1. Understand the relationship between moles and atoms: - 1 mole of any su
32.80 g of Cu × 1 mol Cu / 63.55 g Cu= 0.52 mol of Cu Step 3: Convert Moles to Atoms Using Avogadro’s Number Once the amount of moles is known, the number of atoms in the formula may be calculated using Avogadro's number. Again, use the ratio format. ...
For moles, the unit is simply moles. The number of atoms is just a number; therefore, it is dimensionless, i.e., it does not have any units. Rearrange the formula to find Avogadro's constant: number of atoms / moles = Avogadro's number So, on the left-hand side, we have no unit...
