You have been given a 200.00 mL canister containing an unidentified gas. After accounting for the mass of the container, you determine the mass of the actual gas is 0.376 g. The pressure gauge on the canister reads 874 mmHg, and the temperature gauge reads 298.15 K. What is the identity of the gas? (R = 0.0821 L∙atm/mol∙K)
1. A sample of gas with an initial volume of 28.4 L at a pressure of 735 mmHg and a temperature of 309 K is compressed to a volume of 14.5 L and warmed to a temperature of 377 K .What is the final pressure of the gas? 2. A cylinder with a moveable piston contains 216 mL of nitrogen gas at a pressure of 1.29 atm and a temperature of 292 K .What must the final volume be for...
GAS LAWS 1. The initial volume of a gas at a pressure of 3.2 atm is 2.9 L What will the volume be if the pressure is increased to 4.0 atm? 2. A balloon is filled with 35 O L of helium in the morning when the temperature is 20.00. By noon the temperature has risen to 45.00. What is the new volume of the balloon? 3. A helium balloon with an internal pressure of 1.00 atm and a volume of 4.50 L...
A cylinder with 25.0 L chlorine gas initially had a pressure of 625 mmHg at 125 degree celsius. Changes in temperature caused volume of the gas to decrease 15,000 mL with new pressure of 1.5 atm. What was the change in temperature in degree celsius, that caused this change?
1. If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be? 2. I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver, where the air pressure is 0.85 atm, what will the new volume of the balloon be? 3. I’ve got...
A sample of helium gas has a volume of 6.30 L at a pressure of 915 mmHg and a temperature of 27 ∘C. please answer the following questions with the information given above. 1.) What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 1630 mL and 349 K if the amount of gas is constant? 2.)What is the pressure of the gas in atm when the volume and...
You have a balloon containing 1.4 L of gas in it at standard temperature and pressure. Which conversion factor would you use to convert this number to moles? 22.4L/1 mole 6.02 * 1023 L/1 mole 11/22.4 mole 1 mole/224L 11/6.02 x 1023 mole
If 13.3 L of gas at a pressure of 8.2 atm is compressed until the gas has a volume of 3.9 L, what will the new pressure be? Be sure to enter a unit with your answer. Answer: A container containing 6.15 L of a gas is collected at 177 K and then allowed to expand to 27.8 L. What must the new temperature be in order to maintain the same pressure? Express your answer in units of K. You...
A sample containing 5.60 g O2 gas has a volume of 33.0 L . Pressure and temperature remain constant. What is the new volume if 0.550 mole O2 gas is added? Oxygen is released until the volume is 10.0 L . How many moles of O2 are removed? What is the volume after 3.00 g He is added to the O2 gas already in the container?
A balloon containing 4.00 moles of N2 gas has a volume of 0.750 L at a pressure of 1.00 atm and a temperature of 27°C. What will the new volume of the balloon be, in liters, if the pressure is doubled to 2.00 atm, the temperature is increased to 127°C, and 1.50 moles of N2 is removed from the balloon? On an airliner, an inflated toy has a volume of 0.310 L at 25°C and 745 mmHg. During flight, the...
