Answer:
Explanation:
We can use Dalton's Law of Partial Pressures:
Each gas in a mixture of gases exerts its pressure separately from the other gases.
In other words, if a gas makes up 3.0 % of the atmosphere, its partial pressure is 3.0 % of the total pressure.
Water, Aquaporins are channels in the membrane that allow water to pass through via osmosis.
(P1V1=nRT1)/(P2V2=nRT2)
Constant temperature → (P1V1)/(P2V2)
688 mm Hg → 0.905 atm
994 mm Hg → 1.30789 atm
500.2 mL → 0.5002 L
(P1V1)/(P2V2)
(0.905)V1/(1.30789)(0.5002)
V1 = 0.72288 L → 722.88 mL
Answer:
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
Explanation:
Given that Kp = 0.116atm
NH₄(NH₂CO₂)(s) ⇄ 2NH₃(g) + CO₂(g)
2x atm xatm
Pt = PNH₃ PCO₂
0.116 = 2x + x
0.116 = 3x
x = 0.116/3
x = 0.039 atm
PNH₃ = 2x =2(0.039) = 0.078 atm
PCO₂ = x = 0.039 atm
Now,
KP = PNH₃² × PCO₂
= 0.078² × 0.039 atm³
= 2.37 × 10⁻⁴ atm³
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
