1. Avogadro's Number
* Avogadro's number tells us the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It's approximately 6.022 x 10²³ particles/mole.
2. Calculation
* To find the number of molecules in 1.46 moles of CaCl₂, multiply the number of moles by Avogadro's number:
1.46 moles CaCl₂ * (6.022 x 10²³ molecules/mole) = 8.80 x 10²³ molecules of CaCl₂
Therefore, 1.46 moles of CaCl₂ contains approximately 8.80 x 10²³ molecules.
