Number of atoms = (Number of moles) x (Avogadro's number)
Here's what each part represents:
* Number of moles: This is the amount of substance you have, expressed in moles.
* Avogadro's number: This is a fundamental constant in chemistry, approximately equal to 6.022 x 10²³ atoms per mole. It represents the number of atoms, molecules, or other particles in one mole of a substance.
Example:
Let's say you have 2.5 moles of carbon. To find the number of carbon atoms:
1. Number of atoms = (2.5 moles) x (6.022 x 10²³ atoms/mole)
2. Number of atoms = 1.5055 x 10²⁴ atoms
Therefore, 2.5 moles of carbon contains 1.5055 x 10²⁴ carbon atoms.
