Illinois Central College CHEMISTRY 130 Laboratory Section: Name SHOW YOUR WORK PRELAB: Exp.7 Evaluation of the Ideal Gas Constant Exercise 7 Page 7 1. Referring to the lab text, if the barometric pressure in the lab is 752 mm Hg at 23°C and the difference in the levels of solution inside and outside the eudiometer tube is 185 mm, calculate the corrected pressure of the hydrogen gas in atmospheres. (Remember to correct for the vapor pressure of water.) 2. If 3.0 moles of nitrogen gas are collected in a 35.0 liter container at 20°C, what would be the pressure exerted on the container, in atmospheres? 3. If a gas collection vessel contains 66.0 grams CO2, 96.0 grams O₂ and 4.0 grams of H₂ and has a total pressure of 1860 mm Hg, what is the partial pressure of the hydrogen gas? 5. Using Avogadro's hypothesis, derive the numerical value any units you like but be sure to include them in your derivation. 4. If 22.0 grams of CO₂ gas are collected over water at 35°C and a total pressure of 790 mm Hg, what volume of dry CO₂ could be obtained. R", the Ideal Gas Constant. Use
