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).
Answer:
60
Step-by-step explanation:
To find the range, you subtract the largest number and the smallest number.
Largest number: 80
Smallest number: 20
80-20=60
Answer:
6
Step-by-step explanation:
The number on the right side of the equal side represents the radius, HOWEVER, it is squared, therefore you must square root it to get 6
Actually they want you to simplify the problem.
The problems answer is:
30 goes into 15; 2 times.
Final Answer: 2
76.3 to the nearest whole number is....
76 (it remains the same because the number behind is a 3 (it isn't 5 or higher)
