On a certain day a laboratory barometer indicates that the atmospheric pressure is 786.2 torr. A sample of gas is placed in a flask attached to an open-end mercury manometer, and a meter stick is used to measure the height of the mercury in the two arms of the U tube. The height of the mercury in the open-end arm is 80.4 mm, and the height in the arm in contact with the gas in the flask is 123.5 mm. What is the pressure of the gas in the flask (a) in atmospheres, (b) in kilopascals?

What pressure permits 25.0 cm3 of neon at 735 mmHg to expand to a volume of 40.0 cm3?
An effusion container is filled with 2 L of an unknown gas. It takes 400 s for the gas to effuse into a vacuum. From the same container under the same conditions--same temperature and initial pressure, it takes 161 s for 2.00 L of O2 gas to effuse. Calculate the molar mass (in grams/mol) of the unknown gas.
A 0.0500-g sample of magnesium is reacted with 25 mL of 3.0 M sulfuric acid as described in the experimental section. The resulting hydrogen gas is collected over water and is found to have a volume of 51.0 ml. Thetemperature is 25 °C and the atmospheric pressure is 760.00 mm Hg. The column of water height inside thegraduated cylinder is found to be 24.0 mm. 4.What is the number of moles of hydrogen gas in the sample?5. What is the number of moles of metal in the sample? 6. What is the calculated molar mass of the metal for this trial? 7. What is the percent error in this determination?
A sample of dichloroethane, a dry cleaning solvent, is vaporized into a 266.4 mL flask at 99.8 oC. Some of the sample leaves the flask through a pinhole through the stopper until the pressure in the flask is the same as the outside pressure. A barometer shows the pressure to be 745.3 torr. When the flask is cooled, the mass of dichloroethane in the flask if measured to be 0.8447 g. Calculate the formula weight of dichloroethane. The elemental analysis of dichloroethane is 24.27% C, 4.07% H, and 71.65% Cl.. What is the molecular formula of dichloroethane?
2.00L of carbon dioxide gas (the main component of the Martian atmosphere) is contained at a pressure of 101.3 kPa at room temperature (21oC) on Earth. The daytime temperature at the equator during summer on Mars is also 21oC. If the atmospheric pressure on Mars is 6.01 mmHg, what volume would the gas occupy on Mars?
A weather balloon is inflated with helium to a volume of 685 L at sea level, where the temperature is 30°C and the barometric pressure is 760. torr. The balloon rises to an altitude of 4500 feet where the pressure is 645 torr and the temperature is 6°C. What is the change in volume (in liters) of the balloon in going from sea level to 4500 feet?
A sample of an ideal gas at 1.00 bar and a volume of 1.91 L1.91 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 60.0 bar,60.0 bar, what was the volume of the sample? Assume that the temperature was held constant.
A student obtained a mass of 0.266 g CO2 during his experiment. The atmospheric pressure was 751.6 mmHg and the laboratory temperature was 24.1 °C. The flask used in the experiment had a volume of 146.5 mL. Calculate the molar mass of CO2 from the data. Hint: You cannot use the molar mass of CO2 in your calculation since this is what you are looking for... You need to used the ideal gas law to determine the number of moles of CO2, then do the ratio of grams of CO2 over moles of CO2 to determine the experimental molar mass of CO2.
A balloon can be stretched to a maximum radius of 10.5 cm. The balloon is filled with 3.0 L of helium gas at a pressure of 755 torr and a temperature of 298 K. The balloon is then allowed to rise. If the balloon bursts at an atmospheric pressure of 431 mmHg, what must the temperaturehave been at that point? The formula for the volume of a sphere is V = 4/3πr3.
In an experiment, 175 mL of nitrogen gas was collected over water at 23.5 oC and 757 mmHg. What mass of nitrogen gas was obtained? At the temperature of the gas (23.5 oC), the vapor pressure of water is 21.8 mmHg.
