When applying Dalton's Law to determine the actual pressure of a gas generated in a laboratory exper — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Options A, B, and C correctly describe the concept of aqueous tension and how Dalton's law is applied to moist gases ($P_{dry} = P_{total} - P_{H_2O}$). Option D is fundamentally incorrect; any subsequent calculations (like applying the ideal gas equation) for the dry gas must use the corrected partial pressure ($P_{dry}$), not the total pressure.
