Understanding Molar Mass: A Foundational Concept

Before we jump into the calculation for Zn3(PO4)2, let's briefly revisit the concept of molar mass. Consider this: 022 x 10²³ particles (atoms, molecules, ions, etc. Even so, the molar mass of a substance is the mass of one mole of that substance, expressed in grams per mole (g/mol). Which means one mole, according to Avogadro's number, contains approximately 6. ). This fundamental constant is crucial for converting between macroscopic quantities (grams) and microscopic quantities (number of particles).

Calculating molar mass involves adding up the atomic masses of all the atoms present in a molecule or formula unit. The atomic masses are typically found on the periodic table, expressed in atomic mass units (amu), which are numerically equivalent to grams per mole (g/mol) for molar mass calculations.

Calculating the Molar Mass of Zn3(PO4)2

Now, let's tackle the molar mass of zinc phosphate, Zn3(PO4)2. This compound consists of three zinc (Zn) atoms, two phosphate (PO4) groups, each containing one phosphorus (P) atom and four oxygen (O) atoms.

1. Find the atomic masses: From the periodic table:

   • Atomic mass of Zinc (Zn): 65.38 amu
   • Atomic mass of Phosphorus (P): 30.97 amu
   • Atomic mass of Oxygen (O): 16.00 amu

2. Calculate the molar mass of the phosphate group (PO4):

   • Molar mass of PO4 = (1 × 30.97 amu) + (4 × 16.00 amu) = 94.97 amu

3. Calculate the molar mass of Zn3(PO4)2:

   • Molar mass of Zn3(PO4)2 = (3 × 65.38 amu) + (2 × 94.97 amu) = 196.14 amu + 189.94 amu = 386.08 amu

Because of this, the molar mass of Zn3(PO4)2 is 386.08 g/mol.
