Answer:
Pressure of O₂ = 0.93 atm
Pressure of krypton = 3.32 atm
Explanation:
This problem can be solved by using Dalton's Law of Partial Pressures, which states that the partial pressure of a component of a gaseous mixture depends on the mole ratio of said component and the total pressure of the gaseous mixture.
Pₐ = Xₐ * Ptotal
P
ₐ - the partial pressure of component a
χ
ₐ - its mole fraction in the mixture
P
total - the total pressure of the mixture
The moles of the two gases are:
moles of O₂ = 11.2/32 = 0.35 moles
moles of krypton = 104.75/83.8 = 1.25 moles
Total moles = 1.25 + 0.35 = 1.6 moles
Xₐ = number of moles of a /total moles in mixture
Pressure of O₂ = 0.35/1.6 *4.25 = 0.93 moles
Pressure of krypton = 1.25/1.6 *4.25 = 3.32 moles
Answer:
It is important to know if a resource is renewable or non-renewable because renewable resources are self-sustaining (unlike non-renewable resources). If a non-renewable resource is used too often, that resource may eventually become non-existant. This can also happen to renewable resources, but it is more difficult.
Answer:
The number of moles of the gas is 9.295 moles or 9.30 moles
Explanation:
We use PV = nRT
Where P = 4.87 atm;
V = 67.54 L
R= 0.0821Latm/molK
T = 158 C = 158 +273 K = 431 K
the number of moles can be obtained by substituting the values in the respective columns and solve for n
n = PV / RT
n = 4.87 * 67.54 / 0.0821 * 431
n = 328.9198 / 35.3851
n = 9.295moles
The number of moles is approximately 9.30moles.
