The term trihydrate refers to the fact that three molecules of water are associated with each formula unit of sodium acetate. The formula unit for sodium acetate trihydrate is NaC2H3O2‧3H2O.
A formula unit is the chemical formula for a compound that can be used in balancing a stoichiometric equation. As this is the lowest possible combination of atomic combination, it is a formula unit.
No, the basic unit for a covalent bond is a molecule and for ionic it is formula units.
it is a formula unit
a molecular formula
No. It is a molecule. The term formula unit is generally reserved for ionic compounds.
For ionic compounds the correct term is formula unit, not molecule.
For sodium chloride the term formula unit is more adequate than molecule; and the formula unit has two atoms.
The term molecule is not adequate for sodium chloride; the recommended term is formula unit.

The formula unit -NaCl - (not a molecule) contain two atoms.
A formula unit is an empirical formula.

The term candle power refers to a unit of measuring luminosity or light. The term candle power is now an obsolete term that was once used in the 1800's.
That's not a valid empirical formula. Assuming you meant aluminum chloride and just didn't know the real formula, it's AlCl3 with four atoms per formula unit.
The term trihydrate refers to the fact that three molecules of water are associated with each formula unit of sodium acetate. The formula unit for sodium acetate trihydrate is NaC2H3O2‧3H2O.
Assuming that the questioner meant "trifluoride" instead of "trifluride", there are four total atoms in the formula unit, AsF3.
