It is an empirical formula.
A formula unit is an empirical formula.
An empirical formula has no data about the structure of a compound.
It has a molecular formula of C10H8 so that would make an empirical formula of C5H4.
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.
The formula for sulfite ion is SO3^2-.
The formula for gallium sulfate is Ga2(SO4)3.
The chemical formula for gallium dichromate is Ga2(Cr2O7)3.
The formula for gallium(III) carbonate is Ga2(CO3)3. The formula for gallium(III) oxide is Ga2O3.
It is an empirical formula.
The empirical formula for C12H12 is CH. The empirical formula represents the simplest whole-number ratio of elements in a compound.
A formula unit is an empirical formula.
It has a molecular formula of C10H8 so that would make an empirical formula of C5H4.
In this instance, the empirical formula is the same as the formula unit: NaNO3
An empirical formula has no data about the structure of a compound.
The empirical formula of water is H2O.
The empirical formula for potassium manganate is KMnO4.
