QUESTION 11
A certain laser uses a gas mixture made of 1.00 g hydrogen gas, 4.50 g hydrogen chloride, and 82.5 g neon. The mixture is in a 37.5-L tank at 23 °C.
Based on the information provided, select all statements that are true.
[R = 0.08206 atm.L/mol K ]
O A. The mole fraction of hydrogen is 0.496.
O B. The partial pressure of hydrogen is 0.321 atm.
O C. The mole fraction of neon is 0.868.
O D. The partial pressure of neon is 2.65 atm.
QUESTION 12
A sample of oxygen gas is collected over water at 23 °C. The "wet" gas had a volume of 6.95 L at a barometric pressure of 951 torr. The vapor
pressure of water at 23 °C is 21.1 torr. What is pressure of the dry gas? How many moles of oxygen are in the sample? [R = 0.08206 atm.L/mol K]
