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).
Distance because it depends on the time
B^2 - 4ac =
b=-5
a=-1
c=2
So then it equals =
(-5)^2 - 4(-1)(2)
-5^2 = Equals 25
the power of 2 is multiplying the same number it's powering. Two negatives = a positive. so 5x5 = 25.
4 x -1 x 2 = -8
4 x -1 = -4 and -4 x 2 = -8.
25 - (-8) = 33
Answer:
240 units²
Step-by-step explanation:
The area of the parallelogram shown = base × height
Base = 16
Height = 15
Plug in the values into the formula:
Area = 16 × 15 = 240 units²
