What Is The Molar Mass Of Na2so4?

The molar mass of Na2SO4 (sodium sulfate) can be calculated by adding the atomic masses of its constituent atoms. The elemental composition of Na2SO4 is 2 sodium atoms (Na), 1 sulfur atom (S), and 4 oxygen atoms (O).

The atomic masses of these elements are:

- Sodium (Na): 22.99 g/mol

- Sulfur (S): 32.06 g/mol

- Oxygen (O): 16.00 g/mol

To calculate the molar mass of Na2SO4, we need to multiply the atomic mass of each element by the number of atoms present in the compound and then add up the results:

Molar mass of Na2SO4 = 2 x (22.99 g/mol Na) + 1 x (32.06 g/mol S) + 4 x (16.00 g/mol O)

= 2 x 22.99 g/mol + 32.06 g/mol + 4 x 16.00 g/mol

= 46.00 g/mol + 32.06 g/mol + 64.00 g/mol

= 142.06 g/mol

Therefore, the molar mass of Na2SO4 is 142.06 g/mol.
