What Is the Molar Mass of Na3PO4

The molar mass of Na3PO4 is about 163.94 grams per mole. The molar mass is derived by adding together the atomic mass of each atom of each element that is contained in the compound, which is known as trisodium phosphate.

Since one molecule of Na3PO4 contains three atoms of nitrogen, one atom of phosphorus and four atoms of oxygen, the total molar mass can be determined by adding 22.98(3) + 15.99(4) + 30.97(1). The atomic mass of each element can be located on the periodic table of elements. Trisodium phosphate is a white solid that is often dissolved for use in cleaning products.
