If 2.1 moles of NaCl is dissolved in a solution with a total volume of 7.3 liters, what is the molarity of the solution? Round to two decimals.
Answer:
The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case:
number of moles of solute= 2.1 molesvolume= 7.3 litersReplacing:
[tex]Molarity=\frac{2.1 moles}{7.3 liters}[/tex]
Molarity= 0.29 [tex]\frac{moles}{liter}[/tex]
The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]
Answer:
M = 0.29 M
Explanation:
We are given;
Number of moles of NaCl; n = 2.1 moles
Total volume of solution; V = 7.3 L
Formula for molarity is;
M = n/L
Thus;
M = 2.1/7.3
M = 0.2878 M
Approximating to 2 decimal places gives;
M = 0.29 M

Mr. Ragusa is approached in his lab by one of his students named Hassan. Hassan had found a bottle of nitric acid that did not have a labeled molarity and wanted Mr. Ragusa to help him find it's molarity. Mr. Ragusa filled a buret to 4.85 mL with 0.30 M NaOH. Mr. Ragusa added 5 mL of the acid to a flask and added some phenolphthalein. Mr. Ragusa hit the titration spot on, and the final volume in the buret was 43.69 mL. What is the concentration of the Nitric Acid?
Round your answer to 2 decimal places. Include a unit in your answer. (ex: 1.2M)
HNO3 + NaOH --> NaNO3 + H2O
Answer:
2.33M
Explanation:
1. First, make sure the equation is balanced. In this case it would be HNO3+NaOH --> NaNO3 + H2O. (it is already balanced here.)
2. Find the initial volume, final volume, the volume of acid, volume of NaOH.
a. Initial Volume: 4.85 mL
b. Final Volume: 43.69
c. Acid (HNO3) Volume: 5 mL
d Volume NaOH: Initial V - Final V --> 43.69 mL - 4.85 mL = 38.84 mL NaOH
3. Find moles of NaOH reacted using the volume from D. Convert this volume into Liters. Multiply the volume of NaOH by molarity of NaOH given to you before. (.30 M NaOH)
a. x mol NaOH/ .03884 L = .30 mol NaOH/ 1 mol = .011652 mol NaOH
4. Now find the moles of acid. The acid given to you in the equation is HNO3. The .011652 mol NaOH is from the moles reacted that you just found. The moles on the right side would be the co-efficient in front of the elements in the equation. Since this equation does not have any coefficients (it's already balanced), it would just be 1.
a. .011652 mol NaOH/ x mol HNO3 = 1 mol NaOH/ 1 mol HNO3.
x = .011652 mol HNO3
5. Now find the concentration, also known as molarity. Divide the .011652 mol by the volume of acid you have been given (5 mL). Before using 5 mL, divide it by 1000 to get the Liter form.
a. .011652 mol HNO3/ .005 L = 2.3304 M HNO3

Is cannabinol soluble in 1-octanol?
Why or why not?
Answer: Uhmmmm this is what i got...-
Explanation:
It is a matter of fact that the hydrophobic (water-hating) oily compounds of cannabinoids such as CBD, THC and others are not water soluble. The term "water soluble" refers to materials which dissolve in water in a homogenous manner by becoming molecules or ions (such as sugar, alcohol, and salt).
how do you solve a stoichiometry?
Answer:
Explanation:
Although stochiometry is very scary loking math it is very easy and and fun to learn.
First Balance the chemical equation (Meaning there are equal amounts of elements at end and begining
Second Convert your units to mols
mols are what allows for stochiometry math to work to know how to find the mols takes practice and knowing when to write the math.
Then from there is just knowing how to go from grams to kg or g to mg and etc
The addition of electron shells results in _______ shielding of electrons from the nucleus.
Answer:
I believe the answer is "increasing"
Answer:
the shielding of electrons.
Explanation:
The nucleus pulls electrons to itself due to the net positive charge on it.As more electronic shell is added, the effect of the pull weakens outward.The inner shell experiences the nuclear pull more than the outer shell electrons.Which best describes the velocity of a person on a merry-go-round? * 1 point zero constant increasing continuously changing
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

Which of these statements is true about the two graphed parallelograms?
Answer:
They are similar, because one can be obtained by dilating the other about the origin with a scale factor of 1/2.
Explanation:
The dilation of a shape is similar to the original shape; this is because the corresponding side lengths are proportional.A scale factor is how many times larger or smaller the image will be relative to the preimage. In other words, multiply the x and y-coordinates by the scale factor to get the coordinate points of the image.The image is dilated by 1/2.
Take a look.
The coordinate labels of the preimage include: A, B, C, and D.
The coordinate labels of the image include: A', B', C', and D'.
Coordinates of point A: (2, 8)
Coordinates of point A': (1, 4)
**The preimage's x and y-coordinates multiplied by 1/2 will give you the x and y-coordinates of the image.**
