D- 31.9988 g/mol
Explanation:
The molar mass of a substance is the mass in grams of one mole of the substance. For a compound, the molar mass is the gram - formula mass or gram - molecular weight. It is determined by the addition of its component atomic masses;
To find molar mass of O₂;
Atomic mass of O = 15.9994g/mol
Molar mass of O₂ = 2(15.9994) = 31.9988g/mol
A water and salt is produced
