Answer:
ΔHf0=ΔHsub+IE+ΔHdiss+EA+U
ΔHf0=108+496+122−349−788=411kJ/mol
The enthalpy change in the formation of an ionic lattice from the gaseous isolated sodium and chloride ions is −788 kJ/mole. That enthalpy change, which corresponds to the reaction Na(g)+Cl(g)→NaCl(s), is called the lattice energy of the ionic crystal. Although the lattice energy is not directly measurable, there are various ways to estimate it from theoretical considerations and some experimental values. For all known ionic crystals, the lattice energy has a large negative value. It is ultimately the lattice energy of an ionic crystal which is responsible for the formation and stability of ionic crystal structures.
For sodium chloride, the Born

If you go on youtube and do a quick search about stoichiometry it really helps, or you can google "stoichiometry practice" and get wonderful worksheets that walk you through everything
Answer is 4 ½ billion.
Scientists think the earth's age is 4 ½ billion. This calculation is based on the radioactive dating. Since the formation of the earth, the time period has been divided into 3 major geological time periods as eon. They are phanerozoic, proterozoic and archean.
