The answer is 33.2 moles of a solute is present in 4.00 L of an 8.30 M solution , Option A is correct .

<h3>What is Molarity ?</h3>

Molarity is defined as the amount of solute (in moles)in per litre of solution.

It is also known as molar concentration of a solution , It is expressed in mol/l

$\rm M =\dfrac{moles \;of\; solute}{Volume \;of \;solution} \\\\\\\rm M = \dfrac{n}{V} \\$

We can rearrange this equation to get the number of moles:

n= M * V

The molarity of solution is 8.3 M and the volume given is 4 litres

the moles will be n = 8.30 * 4 = 33.2 moles

Therefore 33.2 moles of a solute is present in 4.00 L of an 8.30 M solution , Option A is correct .

When the reaction mixture is worked-up, it is first washed three times with 5% sodium bicarbonate, and then with a saturated nac

Ann [662]

Solution:

After the reaction of mixture is worked-up Washing three times the organic with sodium carbonate helps to decrease the solubility of the organic layer into the aqueous layer. This allows the organic layer to be separated more easily.

And then the reaction washed by saturated NACL we have The bulk of the water can often be removed by shaking or "washing" the organic layer with saturated aqueous sodium chloride (otherwise known as brine). The salt water works to pull the water from the organic layer to the water layer.

An atom has 5 neutrons,2electrons and 4 protons what type of atom is it

satela [25.4K]

Answer:

Cation

Explanation:

Since the protons are greater than electrons, this means the atom has a net positive charge on it and is now called a cation.

As there are 4 protons, this means that the outermost shell has 2 valence electrons 2s1, 2s2 and this is Group 2 element. Looking at Periodic table, we find that this is beryllium 4Be5 and is denoted as Be^2+

In lab (write this down in your lab protocol), you will be given a stock solution that has a glucose concentration of 60 mg/dL.

Wittaler [7]

Answer:

1. The dilution factor for the serial dilution = 2

2. V2 = 1 mL

3. V1 = 0.5 mL

Explanation:

1. Dilution factor is the ratio of the initial concentration to the final concentration.

Dilution factor = initial concentration / final concentration

First dilution: initial concentration = 60 mg/dL

final concentration = 30 mg/dL

Dilution factor = 60 mg/dL / 30 mg/dL = 2

Second dilution: initial concentration = 30 mg/dL

final concentration = 15 mg/dL

Dilution factor = 30 mg/dL / 15 mg/dL = 2

Therefore, the dilution factor for the serial dilution = 2

2. From the dilution formula, C1V1 = C2V2; V2 = final volume to be prepared.

Since 1 mL of the various glucose solutions are to be prepared, the final concentration, V2 = 1 mL

3. From the dilution formula, C1V1 = C2V2; V1 = initial concentration of the solution to be prepared.

C1/C2 = V2/V1

Since the dilution factor, C1/C2 is 2, V2/V1 = 2

V1 = V2/2

V1 = 1 mL / 2

V1 = 0.5 mL
