I’m not 100%sure but I think it would be indirect
1 lb=453.592 grams

In the analysis of the molecular formula of organic molecules, the degree of unsaturation (also known as the index of hydrogen deficiency (IHD), double bond equivalents, or unsaturation index) is a calculation that determines the total number of rings and π bonds
Answer:
732.9 mmHg
Explanation:
At the eudiometer tube is the mixture of water and hydrogen gas (H₂), by Dalton's law of the partial pressure, the total pressure of a gas mixture (barometric pressure) is equal to the sum of the partial pressures of the components of the mixture:
Ptotal = Pwater + Phydrogen
752.3 = 19.4 + Phydrogen
Phydrogen = 752.3 - 19.4
Phydrogen = 732.9 mmHg
