Which of the following samples will have the lowest pressure if they are all at the same temperature and in identical containers (same volume)? 15 g Rn 15 g He 15 g CO2 15 g H2 All of these samples will have the same pressure

A mixture of carbon dioxide and helium gases at a total pressure of 798 mm Hg contains carbon dioxide at a partial pressure of 243 mm Hg. If the gas mixture contains 2.84 grams of carbon dioxide, how many grams of helium are present?   A mixture of methane and krypton gases contains methane at a partial pressure of 658 mm Hg and krypton at a partial pressure of 307 mm Hg. What is the mole fraction of each gas in the mixture?XCH4 = XKr =

A soda manufacturing company is experimenting with changing the taste of its product as the concentration of carbon dioxide changes. To track their results, they must determine how concentration changes with pressure. The concentration of CO2 under a partial pressure of 0.855 atm is 422.9 ppm. At what pressure (in atm) would the CO2 need to be so that the concentration of CO2 is 212.7 ppm at the same temperature? Report your answer to the thousandths place and do not include units.

Refrigerators are usually kept at about 5ﾟC, when Room temperature is about 20ﾟC. If you were to take an empty 2 liter soda bottle at Room temperature and place it in the fridge, would you expect it to contract to 1/4 its original volume?

An organic compound with the formula CxHyOz is analyzed and contains 40.00 %C and 6.71 %H by mass. A 25-mg sample is vaporized and found to occupy a volume of 3.11 mL at STP. What are the empirical and molecular formula(s) for this compound?

At constant volume, the temperature of a sample of sulfur dioxide gas is decreased from 97 oC to 27 o What was the original pressure of the gas, in atmospheres, if this action decreases the sample pressure to 3.00 atm?

1) An aerosol can with a volume of 0.55 L has a bursting point of 2.6 atm. If the can contains 1.0 g CO₂ (44.01 g/mol) and is heated to 400°C, will it burst? What is the density of the CO(g)

A typical barometric pressure in Denver, Colorado, is 608.8 mm Hg. What is this pressure in kPa?
