How many liters will 5.00 moles of an ideal gas take up at STP?

I have a bag that contains 976 mL of air at room temperature (25 oC) and has a pressure of 795 torr. If I ascend a mountain and the bag does not break, what is the volume in liters (L) when the pressure is 553 torr and the temperature is 10. oC?,,

Suppose I gave you a balloon that contains 7.2 L of gas. If I tell you that originally, the balloon's volume was 1.4 L and that it contained 2.3 moles of gas, how many moles did I add to it before giving it to you?

The pressure in a container has decreased by 10 times, while the volume increased by 5 times from the original volume. The temperature now reads -123.15 °C. What was the starting temperature when I left (in °C)?,,

Suppose you have a fixed container containing 2.48 moles of gas. If the container volume is 30.0 L, and the pressure is 2.05 atm, what is the temperature (°C)? (R = 0.0821 L∙atm/mol∙K)

Which of these is not a correct statement based on what you know about the kinetic molecular theory as it relates to gases?

A 0.325 L canister containing a gas has a pressure gauge reading 721 mmHg, and the temperature gauge reads 305.15 K. The piston on the canister was pushed to compress the gas to 0.286 L, thereby increasing the pressure to 901 mmHg. What is the new temperature in Celsius?

The barometer indicates the pressure is 1520.0 mm Hg. What is this pressure expressed in atmospheres?

You have a 6.75 L container of pure gaseous oxygen at a constant pressure of 1.25 atm. If the temperature is 298 K, calculate the number of grams of oxygen (O2) gas in the container. (R = 0.0821 L∙atm/mol∙K)

Suppose you are holding a container of gas, and the container has a fixed volume (i.e. it won't stretch or give to allow for expansion or contraction). If the gas pressure in the container has doubled while you were holding it, then what must have happened to the temperature?

Which of the following accurately describes the relationship between pressure and volume of an ideal gas?

I have a hot air balloon that has 18.0 g Helium gas inside of it. If the pressure is 2.00 atm and the temperature is 297K, what is the volume of my balloon?

I have a cylinder sitting in my lab that contains 0.7500 L of gas, and it's pressure is 16.24 psi. If I relieve the cylinder and change the pressure to 6.961 psi, what will be the new volume of the gas in L?

A 350.0 mL sample of gas in an flexible container that has a temperature of 293.15 K. Suppose you throw it on the stove and heat it to 373.15 K. What will the new volume be (L)?

My barometer is reading 1253 torr. What is the pressure in mmHg?

The starting volume of a pressure cooker was 1.00 L. The volume increased to 1.10 L, and thermometer read 528.15 K. What was the starting temperature (°C)?

The partial pressure of oxygen gas in our atmosphere is 0.21 atm. This is the partial pressure at which human lungs have evolved to be able to breathe this gas. A SCUBA diver, will thus still have to breath oxygen at this pressure even when diving way down in the water. If a mixture of helium and oxygen (heliox) in his tank is at a pressure of 7.00 atm, what must the partial pressure be of helium to keep the partial pressure of oxygen at 0.21 atm?

The air that we breathe is actually a mixture of several gases. Of those involved, which is the third most abundant component of the mixture?

If you drop Mg into HCl, you will evolve hydrogen gas. If you perform this reaction over water at a temperature of 298.15 K at a pressure of 0.977 atm, and the vapor pressure of water at this temperature is 0.0313 atm, what is the pressure of hydrogen?

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)

I'm looking at the barometer in my lab as I type this question. It says the pressure is 968 torr. What is this pressure expressed in atm?
