The dosage of 22mg can be prepared using approximately 1.222 mL of the 36mg per 2 mL strength solution.

To calculate the dosage using ratio and proportion, we can set up a proportion based on the strength of the solution.

40mg in 2.5 mL solution will be used to prepare a 26mg dosage.

Let X represent the mL of the solution needed to prepare the 26mg dosage.

We can set up the proportion as follows:

40mg/2.5mL = 26mg/X mL

Cross-multiplying and solving for X, we have:

40mg * X mL = 2.5mL * 26mg

40X = 65

X = 65/40

X ≈ 1.625 mL

A liquid is allowed to evaporate and leaves no residue. It can not be determined whether it was an element, a compound, or a mixture.

A water vapor molecule stays roughly 10 days in the atmosphere after it has evaporated. Water vapor starts to cool back down as it ascends higher in the atmosphere. The water vapor condenses when it becomes cold enough, turning it back into liquid water. Eventually, individual water droplets will condense to create clouds and precipitation.

It is not possible to determined whether it would be an element, a compound and mixture because the size of the particle will be too less.

A method for separating homogenous mixtures with one or even more dissolved salts is called evaporation. The procedure separates the liquid from the solid components. Usually, the procedure entails heating the combination until there is no more liquid is present.

Therefore, it can not be possible to determined whether it was an element, a compound, or a mixture by evaporation.

A current of 5.00 A would have to be applied for approximately 39 minutes to plate out 7.70 g of copper from a Cu(NO₃)₂ solution.

To plate out 7.70 g of copper from a Cu(NO₃)₂ solution with a current of 5.00 A, the amount of time required can be calculated using Faraday's law. The equation states that the amount of substance produced (in moles) is directly proportional to the amount of electric charge passed through the solution. The constant of proportionality is known as the Faraday constant, which is equal to 96,485 coulombs per mole.

Using the molar mass of copper (63.55 g/mol), we can calculate the number of moles of copper that would be plated out as 0.121 moles (7.70 g / 63.55 g/mol). To calculate the amount of electric charge required, we can use the formula Q = I x t, where Q is the electric charge in coulombs, I is the current in amperes, and t is the time in seconds.

Thus, we can calculate the time required as follows:
Q = I x t
t = Q / I

The amount of electric charge required to plate out 0.121 moles of copper is:
Q = 0.121 moles x 96,485 C/mol = 11,680 C

Therefore, the time required is:
t = 11,680 C / 5.00 A = 2,336 seconds

Converting seconds to hours, we get:
t = 2,336 s / 3600 s/hour = 0.648 hours (or approximately 39 minutes)

Therefore, a current of 5.00 A would have to be applied for approximately 39 minutes to plate out 7.70 g of copper from a Cu(NO₃)₂ solution.

When the pool's center is occupied by the rubber raft. Think of it as the raft's starting position.

Once it reaches the rubber raft, the raft will start to rise when the friend creates a wave by slapping the water.

The raft will really gain energy from the wave, moving upward.

The raft will return to its original place once the wave passes.

The raft will return to its original place where it was before the wave hits it because it is indicated in the question that it is immobile.

As a result, the wave won't take it to the pool's edge.

Because you are only lightly lifted by the waves or because Lee cannot be pushed to the other side of the pool, the wave won't drive the person on the raft over the edge of the pool.

Entropy is a measure of the disorder or randomness of a system. It is a thermodynamic property that is often used to describe the amount of energy that is unavailable to do work in a system.

A way to describe the second law of thermodynamics, which states that entropy always increases over time in an isolated system.

Entropy can be defined mathematically as S = k * ln (W) where S is entropy, k is the Boltzmann constant, and W is the number of microstates (possible arrangements of the system) that correspond to a given macrostate (overall condition of the system).

A common example of entropy is the process of heat transfer from a hot object to a cold object. As heat is transferred, the hot object loses energy and becomes cooler, while the cold object gains energy and becomes warmer.

This process increases the entropy of the overall system, as the energy   that was once concentrated in the hot object becomes more spread out and disordered.

Another example of entropy is the process of mixing two different substances, such as water and oil. Before they are mixed, the water and oil are in separate regions of the container, but after they are mixed, the molecules of water and oil are randomly distributed throughout the container.

This process increases the entropy of the system, as the molecules are now in a more disordered state.

Sucralose is present in the sample at a mass percent of 97.35 % and vitamin C at 2.65%

We can calculate the moles from osmotic pressure formula

Π = iMRT (Osmotic pressure) 

Van't Hoff factor i = 1

moles/volume = M

Now,

ππ= inVRT ——> (1)

R = 0.0821 L.atm.K.mol⁻¹

T = 301K

Volume = 28 ml, or 0.028 liters.

Next, using equation (1)

n = (π × 0.028 L) / (1× 0.0821 L.atmK⁻¹mol⁻¹× 301 K)

Mole = 0.00356 moles.

Given the quantity of samples and that sucralose has a mass of Y g and vitamin C has a mass of X g,

e = 1.371 g

X + Y = 1.371  g

Y = 1.371  g - X ----> (2)

The mass percent of vitamin c is 39.34 % and sucralose is 60.66 % in the sample.

Since vitamin C (VC) has a molecular mass of 176 g/mol while sucralose has a molecular weight of 398 g/mol. The sum of the moles of VC and sucralose is therefore the total amount of moles.

0.00356 moles = X/176 + (1.371 - X)/398

70,048(0.00356) = 398 X + 176(1.371 - X)

249.37 = 398 X +241.296 - 176 x

8.074 = 222x

X = 0.0364 gram (vit c)

Now, using eq (2);

Y =  1.371g - 0.0364 g

Y = 1.3346 gram (sucralose)

Thus, Vitamin C Mass Percentage is equal to 0.0364 g x 100 / 1.371g.

= 2.65%

Sucralose mass % =  1.3346g 100 / 1.371g

= 97.35 %
