Answer:
mole fraction of toluene 0.53
Explanation:
given data:
vapor pressure of benzene = 160 torr
vapor pressure of toluene = 50 torr
mole of benzene = 3.8 mol
mole of toluene = 5.7 mol
calculate total pressure
here total pressure = mole fraction of toluene x vapour pressure of toluene + mole fraction of benzene x vapor pressure of benzene
mole fraction of toluene
mole fraction of Benzene
= 94 torr
we have mole fraction of toluene in vapor phase =\frac{50}{94} =
= 0.53 (ans)
We can solve this using the Law of Conservation of Momentum. If both marbles are in our system, the initial momentum should equal the final momentum.
The initial momentum can be solved for as so:
* 
+ 
= 
(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]
So if the system has an initial momentum of 0.042, it should have the same final momentum.
(0.06)(-0.2) + (0.03)(
) = 0.042
(0.03)() = 0.54
() = 18 [m/s]
The initial momentum can be solved for as so:
(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]
So if the system has an initial momentum of 0.042, it should have the same final momentum.
(0.06)(-0.2) + (0.03)(
(0.03)(
