It is impossible to know the mass of a large ionic lattice.
Ionic compounds form crystal lattices, not molecules. The term formula unit is used to indicate the simplest whole-number ratio of ions in the compound.
Because an ion is not a molecule.
More correct KCl is the formula unit of potassium chloride.
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
Since carbon monoxide is not an ionic compound it technically doesn't have an ionic formula. The molecular formula for carbon monoxide is CO
Because Na2SO4 is an ionic compound and so does not have actual molecules.
Molecular
No; the compound with the formula NH4Br is an ionic compound.
More correct KCl is the formula unit of potassium chloride.
NaHCO3. Note that since this compound has ionic bonds, it does not strictly have molecules but instead has "formula units.
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
Magnesium oxide is an ionic compound with the formula MgO.
The term formula mass is generally defined as the mass of a unit cell in an ionic compound. Molecular compounds are just defined in terms of molecular mass.
NH4Cl (it stays together with ionic bonds)
Since carbon monoxide is not an ionic compound it technically doesn't have an ionic formula. The molecular formula for carbon monoxide is CO
Ammonia is a molecular compound and not ionic.
Molecular, specifically an organic compound with the general formula: CH3(CH2)3OH
Sort of, though the term "chemical formula" is more accurate for describing compound molecular or otherwise.
Lithium oxide does not exist as molecules, as it is an ionic compound.
