How do you get moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
How many molecules is a mole?
The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.
Why do scientists use moles?
The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. A mole of something represents 6.022×1023 items. Whether it be atom, molecule or formula unit.
How do you get rid of moles on your body?
Using onion juice can also help you to get rid of moles. Peel the onion, chop them into small cubes, and then extract the juice.
