Molarity can be defined as the number of moles of solute in 1 L of solution.
M = n/V
Where M is the molarity of the solution (M or mol/L), n is the moles of the solute (mol) and V is the volume of the solution (L).
Here, solute is KF.
n = <span>0.250 mol
</span>V = 0.500 L
M = ?
By applying the formula,
M = 0.250 mol / 0.500 L
M = 0.500 mol/L
Hence, the molarity of KF solution is 0.500 mol/L.
Answer:
The effect is the increasing of the molar concentration.
Explanation:
When you standarize a solution of NaOH with KHP you are establish its molar concentration (That is the amount of moles of NaOH per liter of solution).
If you evaporated some water of the solution, you are increasing its concentration because volume is decreasing doing the amount of moles per liter increasing.
Answer:
Hey there! :)
Explanation:
Answers;
165lbs = 74842.74
12.01cm = 0.1201
………………….……………………………………
(Answers will be explained)
~So first let’s do question ‘A’
A. 165 lbs=?? g
~We have to use the formula.
Grams=Pounds X 453.59237
(Note: 1 lb = 453.59237)
~With that being said, we can see that the pounds in 165. So we have to multiply using the formula.
~165 X 453.59237
⇒ Equals to 74842.74
So question ‘A’ is 74842.74
==================================================
~Okay now let’s do question ‘B’
B. 12.01 = ?? m
~Let’s first see what the formula is.
~Meters = Centimeter * 0.01
Or...
~Meter = Centimeter / 100
(Note: 1 m = 100 cm)
~Okay now let’s use the formula to find the answer.
(We use the formula)
12.01 / 100
⇒ Equals to 0.1201
~Hope this helps!~
