CHEM107 Take Home Quiz 1 Gases NAME anyah ward 50 points DATE 1/19/2023 Answer the following questions showing all work along with all formules/equations/derivations used. No step by step work, no credit! Due Tuesday 1/24/23. 1. What volume will a sample of oxygen gas occupy in a syringe at 1500mmHg, if the oxygen gas has a volume of 35.0 ml. at 2.3 atm? 2. Sketch the graphical representation of Boyle's law and mention 2 real life application of the law (No need to use graph sheet) 3. Sketch the graphical representation of Caylussac's law and mention 2 real life applications of the law. (No need to use graph sheet) 4. A sample of gas initially has a volume of 859 ml. at 565 K and 2.20 atm. What pressure will the sample have if the volume changes to 268 ml. while the temperature is increased to 815 K? 5. A 0.565 g sample of an unknown compound occupies 345 ml. at 25°C and 3.22 atm. What is the molar mass of the unknown compound? R-82.01mlammol 6 A mixture of 2.0 g of Xenon (Xe) gas and 3.0g of Argon (Ar) gas has a total pressure of 40.5 atm. What is the partial pressure of each gas? 7. If a 50.0 L tank contains 60g He gas and 85.6g CO; gas at 135 °C calculate the total pressure of the gas mixture in the tank? R-0.0821Latmmol K 8. Rank the following 4 gases from least dense to most dense at STP and clearly explain your answer. Br SO, Ar, N₂. 9. A gas tank contains 2 gases PO, and CO. If 0.029 moles of P/O. effuses through a pinhole in the tank in 3seconds, how many moles of CO₂ would effuse in that same amount of time. 10.
