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:
1.54 moles * 6.022 x 10²³ atoms/mole = 9.28 x 10²³ atoms
Therefore, there are approximately 9.28 x 10²³ atoms in 1.54 moles of Bromine.
