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).

Step-by-step explanation:
Answer:
x = 20
Step-by-step explanation:
angle 2 and 3 are congruent, becaus they are alternate interior angles. So, 3x-10 = x+30, 2x = 40, x= 20.
Answer:
Volume of the ball = 2.48 inch³
Step-by-step explanation:
A golf ball is in the shape of a sphere.
Therefore, volume of the ball will be given by,
Volume = 
Here, r = Radius of the ball
By substituting the value of 'r' in the formula,
Volume of the golf ball = 
= 
= 
= 2.482 inch³
≈ 2.48 inch³
