A small piece of zine reacts with dilute Hcl to form H₂ which is
collected over water at 16 c. into a large flask. The total pressure
is adjusted to brometric pressure 752 totr. and volume is
1495 ml.find the pressure of H2 and mass of H2​

Answer:-

I assume that is vapor pressure of water.

Total pressure (752 torr) = Partial pressure H2 + partial pressure of H2O.

Look in the table at 16 C and pick up the vapor pressure of water (partial pressure of water), subtract that from 752 to find the partial pressure hydrogen.then try using PV = nRT. You know P, V, R, and T, Calculate n = number of moles. Then mols dry gas x molar mas = grams.
