We should first convert 23 1/2 million dollars to a mixed number:
Then we need to divide this by 4, since 4 people won an equal amount of the prize:
And to solve this, we must multiply both the numerator and the denominator by . This will then cancel out the 4 in the denominator:
This is the amount each individual person won; we must convert this to a mixed number since the question asked us to:
So now we know that each person won million dollars.
Answer:
The morality of the solution is calculated as 0.859 m. We are required to determine the freezing point depression constant of pure water. The freezing point depression of the solution is given as
* (morality of solution)
and
are the freezing points of the pure solvent (water, 0°C) and
= freezing point depression constant of water. Therefore,
*(0.859 m)
=====> (0°C) – (3.00°C) =
=====> -3.00°C =
Ignore the negative sign (since is positive) and get
= (3.00°C) / (0.859 m) = 3.492°C/m
The freezing point depression constant of the solvent is 3.5°C kg/mole
3.5 K.kg/mole (temperature differences are the same in Celsius and Kelvin scales).
