What is the equation for concentration with Solutes and Solvents?​

Chemistry
1 answer:
QveST [7]3 years ago
5 0

Answer:

 Molarity = no. of moles of solute / Liter of solution

  Molality = no. of moles of solute / Kilogram of solvent

Explanation:

Solvent: Solvent is a liquid that dissolve the solute. in most cases it is water but some time other liquids gases can also be a solvent.solvent have the ability to dissolve solute and in larger volume than solute.

Solute:

It is the substance that is in less amount than solvent and dissolve in it

Solution:

When solvent and solute combines, the solute get dissolved in it and it form a solution.

Concentration:

It is to represent or describe the property of solution and refer to the amount of one constituent per total mixture or solvent.

There are two terms to represent the concentration in terms of solute and solvent.

Molarity:

It the amount of solute in moles dissolved per liter of solution. it can be represented by the following equation

         Molarity = no. of moles of solute / Liter of solution

Molality:

It is the amount of solute in moles dissolved per kilogram of solvent. it can be representd by the following equation

           Molality = no. of moles of solute / Kilogram of solvent

statuscvo [17]

<u>Answer:</u> The value of K_{eq} is 0.044

<u>Explanation:</u>

We are given:

Initial moles of methane = 4.10\times 10^{-2}mol=0.0410moles

Initial moles of carbon tetrachloride = 6.51\times 10^{-2}mol=0.0651moles

Volume of the container = 1.00 L

Concentration of a substance is calculated by:

\text{Concentration}=\frac{\text{Number of moles}}{\text{Volume}}

So, concentration of methane = \frac{0.0410}{1.00}=0.0410M

Concentration of carbon tetrachloride = \frac{0.0651}{1.00}=0.0651M

The given chemical equation follows:

                    CH_4(g)+CCl_4(g)\rightleftharpoons 2CH_2Cl_2(g)

<u>Initial:</u>          0.0410    0.0651

<u>At eqllm:</u>     0.0410-x   0.0651-x       2x

We are given:

Equilibrium concentration of carbon tetrachloride = 6.02\times 10^{-2}M=0.0602M

Evaluating the value of 'x', we get:

\Rightarrow (0.0651-x)=0.0602\\\\\Rightarrow x=0.0049M

Now, equilibrium concentration of methane = 0.0410-x=[0.0410-0.0049]=0.0361M

Equilibrium concentration of CH_2Cl_2=2x=[2\times 0.0049]=0.0098M

The expression of K_{eq} for the above reaction follows:

K_{eq}=\frac{[CH_2Cl_2]^2}{[CH_4]\times [CCl_4]}

Putting values in above expression, we get:

K_{eq}=\frac{(0.0098)^2}{0.0361\times 0.0603}\\\\K_{eq}=0.044

Hence, the value of K_{eq} is 0.044

Why is carbon ideal for making different compounds?
In-s [12.5K]

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

What is the difference between an atom an ion how to determine the charge
Eduardwww [97]

Explanation:

When an atom's outermost orbital gains or loses electrons (also known as valence electrons), the atom forms an ion. An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion
