An oxygen tank contains oxygen (o2) at a pressure of 2.50 ATM. 1- what is the pressure in the tank in torr 2- what is the pressure in the tank in mm hog?
Page 2 of 3 5. What is the pressure in atm of a sample of 25.0 g of argon gas in a 4.00 L container and a temperature of 27°C? (10 pts) 6. What is the volume of a sample of 64.0 g of oxygen gas at a pressure of 745 torr and a temperature of 25.0°C? (10 pts) 7. How many grams of neon are in a 20.0 L steel tank at a pressure of 987 torr and a...
A tank contains 25.0 kg of helium gas at a gauge pressure of 8.00 atm. What is the new gauge pressure after 5.0 kg of helium has been released to fill balloons? Assume the release is slow enough that the tank does not cool down. I am posting this because this question is listed three times on this website with three different answers (1.6 atm, 6.4 atm, and 10.25 atm)! They each say they have the right answer? Please take...
Oxygen used in respiratory therapy is stored at room temperature under a pressure of 150 atm in a gas cylinder with a volume of 60.0 L. If the oxygen flow to the patient is adjusted to 6.00 L/min at room temperature and 0.720 atm , how long will the tank of gas last? Express your answer with the appropriate units. I DO NOT KNOW WHAT TO DO?
A 25.0-L steel tank at 20.0°C contains acetylene gas, C2H2, at a pressure of 1.39 atm. Assuming ideal behavior, how many grams of acetylene are in the tank?
1. What is the pressure of a 50.0L tank that contains 4.04kg of oxygen, O2, at 23°C? Assume that the Ideal Gas Law is obeyed and use R=0.0821 L atm/mol K (Show ALL Work) 2. What is the pressure of a 50.0L tank that contains 4.04kg of oxygen, O2, at 40°C? Assume that the Ideal Gas Law is obeyed and use R = 0.0821 L atm/mol K (Show ALL Work)
A tank of oxygen holds 30.0 L of oxygen (O2) at a pressure of 26.0 atm. When the gas is released, it provides 400. L of oxygen. What is the pressure of this same gas at a volume of 400. L and constant temperature? Express your answer with the appropriate units.
A gas is placed in a storage tank at a pressure of 30.1 atm at 49.5 °C. As a safety device, a small metal plug in the tank is made of a metal alloy that melts at 126 °C. If the tank is heated, what is the maximum pressure that will be attained in the tank before the plug melts and releases gas?
A gas is placed in a storage tank at a pressure of 25.5 atm at 61.2°C. As a safety device, a small metal plug in the tank is made of a metal alloy that melts at 127 °C.If the tank is heated, what is the maximum pressure that will be attained in the tank before the plug melts and releases gas?
Increase the air pressure of a sealed fish tank to 2 atm from 1 atm by pumping in extra air What is the partial pressure of oxygen with 1 atm air before the pressure increase (suppose air has 20% oxygen)?
