Answer:
-2.74°C
Explanation:
From the formula;
∆T= Kf m i
Where Kf= freezing constant of water
m= molality of the solution = number of moles of solute/ mass of solvent in kilogram
Since number of moles of solute = 3.68 mol and mass of solvent= 2.5Kg
m= 3.68/2.5 = 1.472
Then the freezing constant Kf= -1.86 as given in the question
Since the solution is not ionic, the Vant Hoft factor (i) = 0
Hence;
∆T= Kf m
∆T= -1.86 × 1.472
∆T= -2.74°C
Independent is what you physically change in the experiment. Does not change on its own.
Dependent is what happens as an effect of the independent.
Control variables are what stay the same thorough out the entire experiment.
Answer:
0.4941, 0.5059
Explanation:
= Partial pressure of nitrogen = 417 mm Hg
= Partial pressure of xenon = 427 mm Hg
Total pressure in the system is given by
Mole fraction is given by
For xenon
or
So, mole fraction of nitrogen is 0.4941 and xenon is 0.5059.
