1. Avogadro's Number
Avogadro's number is a fundamental constant in chemistry, representing the number of atoms or molecules in one mole of a substance. It's approximately:
* 6.022 x 10²³ particles/mole
2. Calculation
To find the number of potassium atoms in 1.83 moles, we multiply the number of moles by Avogadro's number:
* Number of atoms = (1.83 moles) * (6.022 x 10²³ atoms/mole)
* Number of atoms ≈ 1.10 x 10²⁴ atoms
Therefore, there are approximately 1.10 x 10²⁴ potassium atoms in a 1.83 mole sample.
