Answer

The molar mass of N₂O₃ = 76.0104 g/mol

Step-by-step explanation:

Using the atomic masses of elements from the periodic table; (N = 14.0067, O = 15.999).

Therefore, the molar mass of dinitrogen trioxide is calculated below.

N₂O₃ = 2(N) + 3(O)

N₂O₃ = 2(14.0067) + 3(15.999)

N₂O₃ = 28.0134 + 47.997

N₂O₃ =76.0104 g/mol

The molar mass of N₂O₃ = 76.0104 g/mol
