1. a) A 5.00-liter rigid steel vessel is filled with 1.20 atm of oxygen gas at 90°C. Determine the mass of oxygen gas in the vessel. b) 0.500 moles of helium gas are then added to the vessel from part (a). Determine the total pressure in the vessel at 90°C after the helium is added. c) Some water is then added to the vessel from part (b) so that a very small amount of liquid water is still present in...
A tank contains 22.0 grams of oxygen, 80.00 grams of helium, and 3.21 moles of hydrogen gases.The mixture has a total pressure of 7.00 atmospheres. Calculate the following. a) How many moles of O2 are in the tank? b) How many moles of He are in the tank? c) Total moles of gas in tank d) Mole fraction of each gas e) The partial pressures of each gas
Consider a mixture of 2.00 g of helium and 10.0 g of xenon atoms in a container with a volume of 1 L. Assume that helium and xenon are ideal gases. (a) If the root mean square speed (vrms or urms in Chapter 9) of helium is 1500 m/s, what is the temperature of the gas? (b) Assuming that the helium and xenon are at the same temperature, what is the root mean squared speed of the xenon gas? (c)...
a. A sample of 1.41 g of helium and an unweighed quantity of O2 are mixed in a flask at room temperature. The partial pressure of helium in the flask is 42.0 torr , and the partial pressure of oxygen is 159 torr. What is the mass of the oxygen in the container? b. Both Jacques Charles and Joseph Louis Guy-Lussac were avid balloonists. In his original flight in 1783, Jacques Charles used a balloon that contained approximately 31100 L of...
Question 2 (0.5 marks) Hydrogen gas, H2, and oxygen gas, Oz, can be reacted to form liquid water. If 2.00 g hydrogen gas and 17.20 g oxygen gas are reacted in a 1.500 L flask at 25.0 °C, calculate the total gas pressure (atm) in the flask at 25 "C. The vapor pressure of water is 23.8 mm Hg. Stoichiometry is involved in this question.
