The molecular weight of Actinium(III) phosphate [AcPO4] is 321.971361998.
Actinium(III) phosphate (AcPO4) is an inorganic compound of three elements: Actinium(III), Phosphorus, and Oxygen. The molecular weight of Actinium(III) phosphate is 321.971361998 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Actinium, Phosphorus, and Oxygen.
CALCULATION PROCEDURE: Actinium(III) phosphate [AcPO4] Molecular Weight Calculation
Step 1: Find the chemical formula and determine constituent atoms and their number in an Actinium(III) phosphate molecule.
From the chemical formula, you will know different atoms and their number in an Actinium(III) phosphate molecule. The chemical formula of Actinium(III) phosphate is AcPO4. From the chemical formula, you can find that one molecule of Actinium(III) phosphate consists of one Actinium (Ac) atom, one Phosphorus (P) atom, and four Oxygen (O) atoms.
Step 2: Find out the atomic weights of each atom (from the periodic table).
Atomic weight of Actinium (Ac): 227 (Ref: Jlab-ele089, Lanl-89, Nist-89)
Atomic weight of Phosphorus (P): 30.973761998 (Ref: Jlab-ele015)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Step 3: Calculate the total weight of each atom present in an Actinium(III) phosphate molecule by multiplying its atomic weight by its number.
Number of Actinium(III) atoms in Actinium(III) phosphate: 1
Atomic weight of Actinium(III): 227
Total weight of Actinium(III) atoms in Actinium(III) phosphate: 227 x 1 = 227
Number of Phosphorus atoms in Actinium(III) phosphate: 1
Atomic weight of Phosphorus (P): 30.973761998
Total weight of Phosphorus atoms in Actinium(III) phosphate: 30.973761998 x 1 = 30.973761998
Number of Oxygen atoms in Actinium(III) phosphate: 4
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Actinium(III) phosphate: 15.9994 x 4 = 63.9976
Step 4: Calculate the molecular weight of Actinium(III) phosphate by adding up the total weight of all atoms.
Molecular weight of Actinium(III) phosphate: 227 (Actinium(III)) + 30.973761998 (Phosphorus) + 63.9976 (Oxygen) = 321.971361998
So the molecular weight of Actinium(III) phosphate is 321.971361998.
