Understanding the Concepts
* Mole (mol): A mole is a unit of measurement that represents a specific number of particles (atoms, molecules, etc.). One mole contains 6.022 x 10²³ particles (this is Avogadro's number).
* NaCl (Sodium Chloride): This is the chemical formula for table salt. One molecule of NaCl contains one sodium atom (Na) and one chlorine atom (Cl).
Calculation
1. Avogadro's Number: You'll need Avogadro's number: 6.022 x 10²³ molecules/mol.
2. Moles to Molecules: Multiply the number of moles by Avogadro's number:
3 moles NaCl * (6.022 x 10²³ molecules/mol) = 1.8066 x 10²⁴ molecules
Answer: There are approximately 1.8066 x 10²⁴ molecules in 3 moles of NaCl.
