Answer 2

To find the molar mass of P₂O₃, we need to know the atomic masses of phosphorus (P) and oxygen (O). The atomic mass of phosphorus is approximately 31.0 g/mol, while the atomic mass of oxygen is approximately 16.0 g/mol.

Since P₂O₃ contains two phosphorus atoms and three oxygen atoms, we can calculate its molar mass as follows:

Molar mass of P₂O₃ = (2 × atomic mass of phosphorus) + (3 × atomic mass of oxygen) = (2 × 31.0 g/mol) + (3 × 16.0 g/mol) = 62.0 g/mol + 48.0 g/mol = 110.0 g/mol

Therefore, the molar mass of P₂O₃ is 110.0 g/mol.
