It is impossible to know the mass of a large ionic lattice.
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
Na2SO4 is not a molecular formula because it represents an ionic compound, sodium sulfate. In ionic compounds, the elements are held together by ionic bonds rather than sharing electrons in covalent bonds like in molecular compounds. The formula Na2SO4 indicates that there are two sodium ions (Na+) for every sulfate ion (SO4^2-).
Anhydrous H2CO3 (carbonic acid) is molecular, not ionic. It does not dissociate into ions in the absence of water.
An ionic compound is not represented by a molecular formula because it does not exist as discrete molecules. Instead, it exists as a three-dimensional array of positively and negatively charged ions held together by ionic bonds. The formula for an ionic compound represents the simplest ratio of the ions present in the 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.
Ionic compounds do not have molecular formulas. Instead, they have empirical formulas that represent the simplest whole-number ratio of ions in the compound. Ionic compounds are formed by the combination of positive and negative ions held together by electrostatic forces.
Lithium oxide does not exist as molecules, as it is an ionic compound.
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.
NH2CO3 is not an ionic compound, it is a molecular compound. It does not contain ions; instead, it consists of covalent bonds between the atoms.
Niacin is a molecular compound with the formula C6H5NO2.
The molecular formula of sulfur dioxide (SO2) is molecular, not ionic. This compound is made up of covalent bonds between sulfur and oxygen atoms, where they share electrons to form the molecule.
