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

slide5
Who developed the Law that states that equal volumes of gas at the same pressure and temp. contain equal numbers of moles.?

Avogadro

slide6

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

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

slide10

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.

slide12
The principle that under similar pressures and temperatures, equal volumes of gases contain the same number of molecules is attributed to

Avogadro
