**Molar mass of Li3PO4 (Lithium phosphate) is ****115.79 g/mol****.**

Well, now you have come to know the molar mass of Li3PO4.

But how can you get this value?

Let me show you the calculation to get the molar mass of Li3PO4 (Lithium phosphate).

If you are a visual learner like me, then here is a short one minute video for you.

## Li3PO4 (Lithium phosphate) Molar Mass Calculation

If you have a periodic table with you, then you can easily calculate the molar mass of Li3PO4 (Lithium phosphate).

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 Li3PO4 (Lithium phosphate).

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 Li3PO4, there are 3 Lithium atoms, 1 Phosphorus atom and 4 Oxygen atoms.

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

You can see that;

The molar mass of Lithium is **6.94 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 Li3PO4, you just have to add the molar mass of all the individual atoms that are present in Li3PO4.

You can see that in Li3PO4, there are 3 Lithium atoms, 1 Phosphorus atom and 4 Oxygen atoms.

**So, Molar mass of Li3PO4 = Molar mass of 3 Lithium (Li) atoms + Molar mass of 1 Phosphorus (P) atom + Molar mass of 4 Oxygen (O) atoms.****= (6.94) 3 + 30.974 + (15.999) 4****= 20.82 + 30.974 + 63.996****= 115.79 g/mol**

**Hence the Molar mass of Li3PO4 is ****115.79 g/mol****.**

I hope you have understood the short and simple calculation for finding the molar mass of Li3PO4.

**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.
