Sodium phosphate is a chemical compound that is widely used in various industries, including food, pharmaceuticals, and detergents. To understand the properties and behavior of sodium phosphate, it is essential to know its molar mass. The molar mass of a compound is the sum of the atomic masses of its constituent atoms.
The chemical formula for sodium phosphate is Na3PO4. To calculate the molar mass of sodium phosphate, we need to know the atomic masses of sodium (Na), phosphorus (P), and oxygen (O). The atomic masses of these elements are approximately 22.99 g/mol for sodium, 30.97 g/mol for phosphorus, and 16.00 g/mol for oxygen.
Calculation of Molar Mass
The molar mass of sodium phosphate can be calculated as follows:
Molar mass of Na3PO4 = (3 x atomic mass of Na) + atomic mass of P + (4 x atomic mass of O)
Molar mass of Na3PO4 = (3 x 22.99 g/mol) + 30.97 g/mol + (4 x 16.00 g/mol)
Molar mass of Na3PO4 = 68.97 g/mol + 30.97 g/mol + 64.00 g/mol
Molar mass of Na3PO4 = 163.94 g/mol
Significance of Molar Mass
The molar mass of sodium phosphate is crucial in various applications, including the preparation of solutions, calculation of concentrations, and determination of the amount of substance required for a particular reaction. Knowing the molar mass of sodium phosphate also helps in understanding its physical and chemical properties, such as its solubility, density, and reactivity.
