1. Waxaan gaasaska ku shubaa weel xiran marka hore waxay leeyihiin mugga V iyo heerkulka T. Heerkulka kama dambaysta ah waa 5/4T cadaadiska kama dambaysta ahna waa 2P. Waa maxay mugga kama dambaysta ah ee gaaska?
La yaqaan:
Mugga bilowga ah (V1 ) = V
Heerkulka bilowga ah (T 1 ) = T
Heerkulka kama dambaysta ah (T 2 ) = 5/4 T
Cadaadiska bilowga ah (P 1 ) = P
Cadaadiska kama dambaysta ah (P 2 ) = 2P

2. Go'aami mugga 2.00 mol ee gaasaska (gaaska ku habboon) ee STP. STP = Heerkulka iyo Cadaadiska Caadiga ah.
La yaqaan:
Moles of gas (n) = 2 moles of ice
Heerkulka caadiga ah (T) = 0 o C = 0 + 273 = 273 Kelvin
Cadaadiska caadiga ah (P) = 1 atm = 1.013 x 10 5 Pa
Joogtada gaaska caalamiga ah (R) = 8.315 Joule/mol e .Kelvin
La Doonayo : Mugga gaasaska (V)

Isle'egta sharciga gaaska ee ugu habboon (tirada burooyinka, n)
Mugga 2 moles oo gaas ah waa 44.8 litir.
Mugga 1 mole oo gaas ah waa 45.4 litir / 2 = 22.4 litir.
Mugga 1 mole ee gaas kasta waa 22.4 litir.

3. 4 litir oo gaas ogsijiin ah ayaa leh heerkul ah 27°C iyo cadaadis ah 2 atm (1 atm = 10 5 Pa) oo ku jira weel xiran. Joogtada gaaska guud (R) = 8.314 J.mol e −1 .K −1 iyo lambarka Avogadro ( N = A ) = 6.02 x 10 23 molecules/mol e . Waa maxay molecules-ka gaasaska ogsijiinta ee ku jira weelka?
La yaqaan:
Mugga gaasaska (V) = 4 litir = 4 dm 3 = 4 x 10 -3 m 3
Heerkulka gaasaska (T) = 27 o C = 27 + 273 = 300 Kelvin
Cadaadiska gaasaska (P) = 2 atm = 2 x 10 5 Pa
Joogtada gaaska guud (R) = 8.314 J.mol e −1 .K −1
Lambarka Avogadro (N A ) = 6.02 x 10 23
La Doonayo : Waa maxay molecules-ka gaasaska oksijiinta ee ku jira weelka (N)
Xalka:
1 mole oo gaasaska oksijiinta ah, waxaa ku jira 1.93 x 10 23 molikula oo oksijiin ah.

4. Weel ay ku jirto gaas neon ah (Ne, cufnaanta atomiga = 20 u) heerkulka iyo cadaadiska caadiga ah (STP ) wuxuu leeyahay mug dhan 2 m 3. Go'aami cufnaanta gaaska neon!
La yaqaan:
Cufka atamka ee neon = 20 garaam/mol e = 0,02 kg/mol e
Heerkulka caadiga ah (T) = 0 o C = 273 Kelvin
Cadaadiska caadiga ah (P) = 1 atm = 1.013 x 10 5 Pascal
Mugga (V) = 2 m 3
La Doonayo : cufka (m) ee gaaska neon
Xalka:
Heerkulka iyo cadaadiska caadiga ah (STP), 1 mole gaas kasta, ku dar gaaska neon, mug leh 22.4 litirs = 22.4 dm3 = 0.0448 m3.
Mugga 2 m 3 , waxaa ku jira 44.6 moles oo gaas neon ah.
Cufka atomiga ee gaaska neon waa 20 garaam/mole.
Taas macnaheedu waa in 1 mole uu ku jiro 20 garaam ama 0.02 kg oo gaas neon ah. Sababtoo ah 1 mole waxaa ku jira 0.02 kg oo gaas neon ah marka 44.6 mole waxaa ku jira 44.6 mole x 0.02 kg/mole = 0.892 kg = 892 garaam oo gaas neon ah.
