What is the total pressure (in atm) inside of a vessel containing N2 exerting a partial pressure of 0.256 atm, He exerting a par
Bezzdna [24]

Answer: Total pressure inside of a vessel is 0.908 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual partial pressures. exerted by each gas alone.

p_{total}=p_1+p_2+p_3

p_{N_2} = partial pressure of nitrogen = 0.256 atm

p_{He} = partial pressure of helium = 203 mm Hg = 0.267 atm  (760mmHg=1atm)

p_{H_2} = partial pressure of hydrogen =39.0 kPa = 0.385 atm  (1kPa=0.00987 atm)

Thus p_{total}=p_{H_2}+p_{He}+p_{H_2}

p_{total} =0.256atm+0.267atm+0.385atm =0.908atm

Thus total pressure (in atm) inside of a vessel is 0.908

A helium balloon has a volume of 2.00L at 101kpa. As the balloon rises the pressure drops to 97.0kPa. What is the new volume?
Mrrafil [7]

Answer:

2.08L

Explanation:

V1 = 2.00L

P1 = 101kPa

P2 = 97.0kPa

V2 = ?

from Boyle's law,

P1V1 = P2V2

101 × 2 = 97 × V2

V2 = 202/97 = 2.08L

Therefore, the new volume is 2.08L
