Question

The lattice energy of sodium chloride crystal is the energy released when 1 mole of NaCl is formed from

Answer 1

Answer:

787.3 kg/mol

Explanation:

Answer 2

Answer:

788 KJ/mol

Explanation:

• Lattice energy is that amount of energy which is required to separate one mole of a solid into its constituents gaseous ions at infinite distances.
• the lattice energy of NaCl is 788 KJ/mol, it means that 788 KJ/mol of energy is required to separate one mole of solid NaCl.
