**Molar mass of Ca3(PO4)2 is ****310.174 g/mol****.**

Well, now you have come to know the molar mass of Ca3(PO4)2.

But how can you get this value?

Let me show you the calculation to get the molar mass of Ca3(PO4)2.

You can also refer to this one minute video which will show you the simple steps to calculate the molar mass of any compounds.

## Ca3(PO4)2 Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of Ca3(PO4)2.

Because the molar mass of any molecule (or compound) can be calculated by simply adding the molar masses of individual atoms.

Now here we have to find the molar mass of Ca3(PO4)2.

So for that, have a look at the periodic table given below.

You can see the molar mass value of all the atoms from this periodic table.

Now in Ca3(PO4)2, there are Calcium atoms, Phosphorus atoms and Oxygen atoms.

So let’s look at the molar mass of Calcium, Phosphorus and Oxygen from the above periodic table.

You can see that;

The molar mass of Calcium is **40.078 g/mol**. ^{[1]}

The molar mass of Phosphorus is **30.974 g/mol**. ^{[2]}

The molar mass of Oxygen is **15.999 g/mol**. ^{[3]}

Now, to calculate the molar mass of Ca3(PO4)2, you just have to add the molar mass of all the individual atoms that are present in Ca3(PO4)2.

**So, Molar mass of Ca3(PO4)2 = (Molar mass of Calcium atom × 3) + {Molar mass of Phosphorus atom + (Molar mass of Oxygen atom × 4)} × 2****= (40.078 × 3) + {30.974 + (15.999 × 4)} × 2****= 120.234 + {30.974 + 63.996} × 2****= 120.234 + {94.97} × 2****= 120.234 + 189.94****= 310.174 g/mol**

**Hence the Molar mass of Ca3(PO4)2 is ****310.174 g/mol****.**

I hope you have understood the short and simple calculation for finding the molar mass of Ca3(PO4)2.

**Remember**

- In some books, you may see the unit of molar mass as grams/mole or g/mole. But all these units (i.e g/mol, grams/mole and g/mole) are the same.
- Always follow the calculation order to avoid any mistakes in calculation. First solve the brackets, then multiplications and at last do the final addition.
- And don’t forget to put the unit g/mol to your final calculated molar mass.
