A 7.73 mass % aqueous solution of ethylene glycol (HOCH2CH2OH) has a density of 1.19 g/mL. Calculate the molarity of the solutio
butalik [34]

Answer:

Molarity for the solution is 1.48 M

Explanation:

Molarity involves the moles of solute that are contained in 1L of solution. It is a sort of concentration. The most usual.

7.73 by mass involves the mass of solute that are contained in 100 g of solution, so this one of ethylene glycol contains 7.73 g of it.

Let's determine the moles of solute

7.73 g / molar mass of ethylene glycol = moles

7.73 g / 62 g/mol = 0.124 mol

If the mass of solution is 100 g, we can determine the volume with density.

Density = Mass / Volume

Volume = Mass / Density

Volume = 100 g / 1.19 g/mL = 84.03 mL

In conclusion, 0.124 moles are contained in 84.03 mL

Molarity is mol/L, so let's convert the volume in L

84.03 mL . 1L / 1000 mL = 0.08403 L

0.124 mol / 0.08403 L = 1.48 M

He nitrogen cycle is one of the most important (and complex!) of the biogeochemical cycles. Why is nitrogen important?
gayaneshka [121]

Nitrogen is an essential part of proteins and nucleic acids (DNA).

<h3>Why is nitrogen important?</h3>

All living things require nitrogen. It is a part of proteins, ATP, chlorophyll, DNA, and RNA. Given that it makes up a significant portion of the structures of biomolecules in living organisms, its synthesis and consumption in the biogeochemical cycle are of highest importance. Proteins are made up of amino acids (NH2 group).

The structural development of living species' genetic material (DNA, RNA) also involves nitrogen. It is a part of the nitrogenous bases, which together with other nucleotides create RNA and DNA.

Therefore, a nitrogen deficit can cause major structural issues for such an organism.

<h3>What happens if nitrogen cycle is disrupted?</h3>

A number of undesirable consequences can result from the nitrogen cycle being disrupted. For instance, an abundance of nitrogen in aquatic systems leads to eutrophication. Acid rain can be caused by a rise in atmospheric nitrogen.

The majority of ecosystems can tolerate low nitrogen levels since the majority of nitrogen is not biologically accessible in nature. Ecosystems become out of balance when humans significantly increase the quantity of nitrogen that is accessible through fertilizers, fertilizer use, and other means.

Explain how you would prepare a solution of sucrose with a molarity of 0.25.
Dimas [21]
Solution of 0.25 M is prepared in two steps,

1) Calculate Amount of Solute:

                                Molar Mass of Solute:  342.3 g/mol

As we know,
                            Molarity  =  Moles / 1 dm³
or,
                            Moles     =  Molarity × 1 dm³
Putting Values,
                            Moles     =  0.25 mol.dm⁻³ × 1 dm³

                            Moles     =  0.25 moles

Now, find out mass of sucrose,
As,               
                            Moles      =   Mass / M.mass
or,
                            Mass       =  Moles × M.mass
Putting Values,
                            Mass       =  0.25 mol × 342.3 g.mol⁻¹

                            Mass       =  85.57 g

2) Prepare Solution:
                               Take Volumetric flask and add 85.57 g of sucrose in it. Then add distilled water up to the mark of 1 dm³. Shake well! The solution prepared is 0.25 M in 1 Liter.
