Answer:
30.4 torr
Explanation:
We have all the information which is required to solve this question ( more than we even need as the molecular weight)
Ptotal = Ptoluene + Pbenzene
Ptotal = Xtoluene Pºtoluene + XbenzenePºbenzene
The mole fraction is given by the formula:
X =number of moles / total number of moles
Xtoluene = 8.53 / (2.15+8.53) = 0.80
Xbenzene = 2.15 / 10.68 = 0.20
⇒Ptotal = 0.80 x 14torr + 0.20 x 96 torr = 30.4 torr
Answer:
decreased osmolality of extracellular fluids
Explanation:
When there is decreased osmolality of extracellular fluids, there will be Volume depletion, or extracellular fluid (ECF) volume contraction, which occurs as a result of loss of total body sodium. Causes include vomiting, excessive sweating, diarrhea, burns, diuretic use, and kidney failure. In this way, sodium loss always causes water loss.
<h3>
Answer:</h3>
0.0108 J/g°C
<h3>
Explanation:</h3>
We are given;
- Mass of the unknown material as 36.359 g
- Quantity of heat is 59.912 J
- Temperature change, ΔT = 152°C
We are required to calculate the specific heat capacity of the material.
- Note that the quantity of heat absorbed is calculated by multiplying mass by specific heat and by change in temperature.
To calculate the specific heat capacity we rearrange the formula;
c = Q ÷ mΔT
= 59.912 J ÷ (36.359 g × 152°C)
= 0.0108 J/g°C
Therefore, the specific heat capacity of the unknown material is 0.0108 J/g°C
Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As,
Therefore, putting the given values into the above formula as follows.
=
= 0.132
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
