Chapter 11b Ideal Gas Laws

- molar amount

- V = nRT
- P
- 0.600mol * 0.0821 (15.0°C +273) = 12.9 L
- 1.10 atm

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

True

Avogadro

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

- diffuses

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

True

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

gas diffusion

molar mass = grams * RT

PV

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

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.
