Phosphorus pentachloride (PCl5) contains 1 phosphorus atom and 5 chlorine atoms.
There are 4 phosphorus atoms in a molecule of P4. Each molecule consists of 4 phosphorus atoms bonded together.
Phosphorus trichloride has 3 chlorine atoms and 1 phosphorus atoms, so it has a total of 4 atoms.
There are 2.21 x 10^24 atoms of phosphorus in 3.65 moles of phosphorus triiodide.
Tetra phosphorus dioxide (P4O8) contains 12 atoms: four phosphorus atoms (each with 1 atom) and eight oxygen atoms (each with 2 atoms).
Im assuming you mean protons because phosphorus is its own atom... but anyway phosphorus has 15 protons in its nucleus
Magnesium phosphide (Mg3P2) contains 2 atoms of phosphorus.
One PCl3has one phosphorus (P) and three chlorine (Cl) atoms, so a total of 4 atoms.So, 3PCl3has three phosphorus (P) and nine chlorine (Cl) atoms, so a total of 12 atoms.
Today are known the phosphorus molecules P2 and P4.
There are 6.022 x 10^23 atoms in one mole of phosphorus.
In 4PCl3 (phosphorus chloride) has 16 atoms in it. One single phosphorus chloride molecule would have four atoms in it. P=1 Cl3=3 1+3=4 4X4=16 atoms
To convert atoms to moles, you divide by Avogadro's number, which is approximately 6.022 x 10^23. Therefore, 1.20x10^25 atoms of phosphorus is equal to 20 moles of phosphorus.
