### Evaluation of the Ideal Gas Constant **Instructions: SHOW YOUR WORK** #### Illinois Central College **CHEMISTRY 130 - Laboratory Section:** --- #### Exercise 7 - Page 7 1. Referring to the lab, if the barometric pressure in the lab is 752 mm Hg at 23°C and the levels of H₂ (gas) 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 25.0-liter container at 20°C, what would be the pressure exerted in the container, in atmospheres? 3. If a gas collection consists of 1.0 grams of CO₂, 6.0 grams O₂, and 4.0 grams of H₂, and has a total pressure of 600 mm Hg, what is the partial pressure of the hydrogen gas? 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? 5. Using Avogadro’s hypothesis, derive the numerical value for “R,” the Ideal Gas Constant. Use any units you like but be sure to include them in your derivation. --- This exercise aims to help students understand the application of the Ideal Gas Law in different scenarios, ensuring they can accurately determine the necessary variables and perform the correct calculations using given conditions.
