Final answer:
The molecular weight of ozone is 48 g mol^-1. Aqueous tension is subtracted from total pressure to find the pressure of dry gas.
Explanation:
Molecular weight of ozone: Ozone has a molecular formula of O3 and a molar mass of 48 g mol^-1.
Aqueous tension is the partial pressure of water vapor in a mixture of gases over water. When determining the pressure of dry gas, aqueous tension is subtracted from total pressure to obtain only the pressure exerted by the dry gas itself.
