due tomorrow please help At 298 K, a 5.0-L flask contains 0.15 mol of O, and 0.22 mol of N. Calculate the partial pressure of N2 inside the container. (note: the ideal gas constant is 0.0821 L atm/mol K) (4 points)
Please help with these two 1. A flask is filled with 1.08 moles of a gas at 20.7 K and 646.8 mm Hg. The flask is then opened and an additional 1.33 moles are added. The temperature of the flask is then changed to 272.4 K. What is the pressure (in atm) of the flask under these final conditions? 2. The density of a gas is 4.22 g/L at a pressure of 1.77 atm and a temperature of 14.66 °C. What...

BG20.2 Determination of the Ideal Gas Law Constant Page 9 of 12 PRELAB QUESTIONS (Show all calculations.) I. Write a balanced chemical equation for the reaction of magnesium with hydrochloric acid. 2. A class ran this lab as described above. One student cut a piece of magnesium ribbon and found that it weighed 0.0347 g. The magnesium reacted with the 4.0 mL of concentrated hydrochloric acid. The concentration of concentrated hydrochloric acid is 12 mol/liter. Which reactant is the limiting...
How many moles of gas are in a container that has a volume of 20.5 mL, temperature of 303 K, and pressure of 1.10 atm? Assume ideal gas behavior. L atm L kPa • Use R-0.08206 mol K vor 8.314 v for the ideal gas constant. mol K • Your answer should have three significant figures.
