Chapter 11b Ideal Gas Laws


When pressure volume and temperature are known the ideal gas law can be used to calculate

When pressure, volume, and temperature are known, the ideal gas law can be used to calculate

  • molar amount


Calculate the approximate volume of a 0 600 mol sample of gas at 15 0 c and a pressure of 1 10 atm

Calculate the approximate volume of a 0.600 mol sample of gas at 15.0°C and a pressure of 1.10 atm

  • V = nRT

  • P

  • 0.600mol * 0.0821 (15.0°C +273) = 12.9 L

  • 1.10 atm


True or false

True or false

  • John Dalton developed the concept that the total pressure of a mixture of gases is the sum of their partial pressures?

True


Chapter 11b ideal gas laws

Who developed the Law that states that equal volumes of gas at the same pressure and temp. contain equal numbers of moles.?

Avogadro


Chapter 11b ideal gas laws

If a gas with an odor is released in a room, it quickly can be detected across the room because it

  • diffuses


True or false1

True or false

  • The law of combining volumes applies only to gas volumes measured at constant temperature and pressure.

True


Chapter 11b ideal gas laws

the odor of perfume spreading throughout a room is an example of

gas diffusion


A 1 00 l sample of a gas has a mass of 1 92 g at stp what is the molar mass of the gas

A 1.00 L sample of a gas has a mass of 1.92 g at STP. What is the molar mass of the gas?

molar mass = grams * RT

PV

1.92g * 0.0821 * (273K) = = 43.0g/mol 1.00 atm* 1.00 L


Chapter 11b ideal gas laws

If two gases are both measured at 725 ˚C and 5.05 atm, what volume of N2 (g) can be produced from the decomposition of 37.6 L of NH3 (g)?

37.6 L

Avogadro’s law: equal volumes of gas contain equal numbers of moles at the same pressure and temp.


Knowing the mass and volume of a gas at stp allows one to calculate the

Knowing the mass and volume of a gas at STP allows one to calculate the


Chapter 11b ideal gas laws

The principle that under similar pressures and temperatures, equal volumes of gases contain the same number of molecules is attributed to
