Respuesta :
The substance with the greatest molecular mass is I₂.
The molecular mass is the sum of the atomic masses of all atoms in a molecule
Let's calculate the molecular mass of each compound to know the greatest.
molecular mass of H₂O₂ = 2 + 32 = 34 g/mol
molecular mass of CF₄ = 12 + (19 × 4) = 12 + 76 = 88 g/mol
molecular mass of NO = 14 + 16 = 30 g / mol
molecular mass of I₂ = 127 × 2 = 254 g/mol
Therefore, the substance with the greatest molecular mass is I₂.
