In the lab, a student collects 0.002702 grams of hydrogen gas over water in a eudiometer at 23°C. The atmospheric pressure is 794 mmHg. **Question:** What volume (in mL) of dry hydrogen gas would be collected?**Volume of dry gas = [ ] mL**### Explanation:This problem involves calculating the volume of dry hydrogen gas collected in a laboratory setting.- **Hydrogen Reaction:** The equation involves magnesium and hydrochloric acid producing hydrogen gas.- **Temperature and Pressure:** Values from the table correspond to different temperatures and their respective water vapor pressures.- **Eudiometer Usage:** The eudiometer measures the volume of gas and needs a correction for water vapor pressure when calculating dry gas volume.

Given : Total pressure of gas = 794 mm Hg Temperature of reaction = 23 oC Vapour pressure of water…
