the chemical formula for a ribose is C12H22O11.
In this instance, the empirical formula is the same as the formula unit: NaNO3
The empirical formula for potassium manganate is KMnO4.
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
The empirical formula of phosphorus selenide is P2Se3.
the chemical formula for a ribose is C12H22O11.
The chemical formula for ribose sugar is C5H10O5.
It is an empirical formula.
CH will be the empirical formula and C12H12 will be the molecular formula
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
It Has No Empirical Formula.
An empirical formula has no data about the structure of a compound.
The empirical formula for potassium manganate is KMnO4.
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
