In this case, the empirical formula and the molecular formula are the same and it is K3PO4.
The chemical formula for potassium phosphate is K3PO4.
CH will be the empirical formula and C12H12 will be the molecular formula
Potassium is K (with a 1+ valence) and the phosphate anion is PO4 (with a 3- valence). Thus, it takes 3 K's for each PO4. The formula for potassium phosphate is K3PO4.
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.
The empirical formula for catechol is C6H6O2.
The chemical formula for potassium phosphate is K3PO4.
This compound doesn't exist; probably you think to a potassium phosphate as K3PO4 or another.
K3PO4
K3po4
Calcium chloride has the formula CaCl2 if anhydrous. Potassium phosphate has the formula K3PO4.
It is an empirical formula.
A formula unit is an empirical formula.
CH will be the empirical formula and C12H12 will be the molecular formula
It Has No 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.
In this instance, the empirical formula is the same as the formula unit: NaNO3
