1. Avogadro's Number
* Avogadro's number tells us the number of particles (atoms, molecules, etc.) in one mole of a substance. It's approximately 6.022 x 10²³ particles/mole.
2. Calculation
* Step 1: Multiply the number of moles by Avogadro's number.
10 moles Na * (6.022 x 10²³ atoms/mole) = 6.022 x 10²⁴ atoms
Answer: There are approximately 6.022 x 10²⁴ atoms in 10 moles of sodium.
