A 68.0 mL portion of a 1.50 M solution is diluted to a total volume of 208 mL. A 104 mL portion of that solution is diluted by adding 161 mL of water. What is the final concentration? Assume the volumes are additive.

Answers

Answer 1

Taking into account the definition of dilution, after two dilutions the final concentration is 0.1923 M.

Dilution

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution. This is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volume

Final concentration

In this case, you know for the first dilution:

Ci= 1.50 MVi= 68 mLCf= ?Vf= 208 mL

Replacing in the definition of dilution:

1.50 M× 68 mL= Cf× 208 mL

Solving:

(1.50 M× 68 mL)÷ 208 mL= Cf

0.49 M= Cf

Now, in a second dilution you take a sample of 104 mL of this diluted solution and add another 161 mL of water. The final volume of the solution will be

Vfinal= 104 mL + 161 mL= 265 mL

The concentration of the 104 mL sample is equal to the concentration of the first diluted solution, this is 0.49 M. Therefore, the concentration of the final solution will be:

0.49 M× 104 mL= Cf× 265 mL

Solving:

(0.49 M× 104 mL)÷ 265 mL= Cf

0.1923 M= Cf

In summary, the final concentration is 0.1923 M.

When solving problems using dimensional analysis, the units cancel out diagonally from each other. T or F

The statement that when solving problems using dimensional analysis, the units cancel out diagonally from each other is TRUE.

What is dimensional analysis?

Dimensional analysis  can be referred to as the analysis of the relationships between different physical quantities by identifying their base quantities and units of measure and tracking these dimensions as calculations or comparisons are performed.

The main idea in Dimensional Analysis is to be able to create a conversion ratio that has the units you want in the numerator and the units you already have in the denominator.

The statement that when solving problems using dimensional analysis, the units cancel out diagonally from each other is TRUE.

Dimensional analysis allows you to convert units by multiplying the old measurement by one (or more) forms of the number 1. While we know that the multiplication by 1 does not change the value of the measurement, it in effect does change the measurement's units.

using the molar ratio between the limiting reactant (aluminum) and the product copper determine the theoretical yield of copper

Answers

Using the molar ratio of the limiting reactant to the product, the theoretical yield of copper would be 192 grams.

What are limiting reactants?

In chemical reactions, limiting reactants are reactants that limit the extent of reactions due to their limited quantities as compared to other reactants.

Thus, limiting reactant dictates the amount of product that is formed from reactions.

Considering the reaction:

[tex]3CuCl_2 + 2Al = 2AlCl_3 + 3Cu[/tex]

Aluminum being the limiting reactant has 2 moles. The copper, being the product has 3 moles. Thus, the mole ratio between the limiting reactant and the product is 2:3.

This means that for every 1 mole of aluminum that reacts, 1.5 moles of copper is produced.

3 moles of copper are produced from the reaction.

Recall that: mass = mole x molar mass

Molar weight of copper = 64 g/mol

Mass of 3 moles copper = 3 x 64

                                      = 192 grams

The theoretical yield of copper is, therefore, 192 grams.

A limiting reagent is a reactant that is entirely consumed in the chemical reaction from the reaction mixture and indicates the completion of the reaction and is known as a limiting reactant.

The limiting reagent will decide the maximum quantity of product when reactants will not take in stoichiometric quantities.

Given, the chemical reaction of the formation of sulfurous acid:

SO₂ (g) + H₂O (l)  → H₂SO₃ (l)

The molecular mass of the sulfur dioxide, water, and sulfurous acid is 64, 18, and 82g/mol respectively.

Given, the amount of sulfur dioxide, and water is 30 g and 8.4 g respectively.

If 18 grams of water react with sulfur dioxide = 64 g

Then 8.4 g  of water reacts with sulfur dioxide = (64/18)×8.4 = 29.86 g

So, water is the limiting reagent in this reaction, which will decide the amount of sulfurous acid.

Donna wants to calculate the speed at which a sound wave is traveling. She knows that the frequency of the wave is 680 hertz and that the wave has a wavelength of 0.5 meters.

What is the speed of the sound wave?

Answers

The speed of the sound wave is 340 mrter per second.

f = frequency of sound wave = 680 hertz

λ = wavelength of sound wave = 0.5 meter

v = speed of the sound wave

We know that the velocity of a sound wave is given by

speed of sound wave = frequency wave of sound x wavelength of sound wave

v = f λ

Substituting the above values into the above equation

v = (680 hertz) (0.5 meters)

v = 340 meters per second

Therefore the speed of sound waves is 340 meters per second.

Sound waves are pressure waves. They can be seen as pressure fluctuations over time. Sound waves are transverse waves. To hear the sound of a tuning fork, the tines on the fork must move air from the fork to the ear. Most sound waves are produced by vibrating objects. Sound is a kind of energy produced by vibration.

Explain Dilution  ?

Dilution is the process of "lowering the concentration of a solute in a solution simply by  adding more solvent, such as water, to the solution." Diluting a solution requires adding a solvent without adding a solute.

A popular way to make a solution of a given concentration is to take a higher concentration  and add water until the required concentration is reached. Dilution is the term for this procedure. Dilution can also be done by mixing a higher concentration solution with a lower concentration. Since stock solutions are often obtained and stored in very concentrated concentrations, dilution of the solutions is a mandatory procedure in the laboratory.
