How many ions in 1 mol of melted Sodium chloride?

Answer 1

Sodium chloride is NaCl. It is made up of sodium ions (Na⁺) and chloride ions (Cl^-). 1 mole of sodium chloride contains 1 mole Na⁺ and 1 mole Cl^-, so there are TWO moles of ions for every 1 mole of NaCl. Now, for the actual NUMBER of ions.

2 moles of ions x 6.02x10²³ ions/mole of ions = 1.2x10²⁴ ions
