<span>Hello @Malikjawadarshad,

"the chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides)." This is the Literal Definition of Organic Chemistry, So I hope it helps. What you need to do, in this case, is state this definition, and everything you have learned to make a "Personal Definition" written by you. Do you get it? I hope so, and if not, contact me!

Thank you,
Darian D. </span>

The molar concentration (M) of a solution prepared by dissolving 0.2362g of Cr(NO3)3 in a 50-mL volumetric flask is 0.01985M, wh

Answer:

Here's what I get

Explanation:

You want to dilute the original solution by a factor of 25 in two steps, so you could dilute it by a factor of 5 in the first step, then dilute the new solution by another factor of 5.

A. First dilution

Use a 10 mL pipet to transfer 10 mL of the original solution to a 50 mL volumetric flask. Make up to the mark with distilled water. Shake well to mix.

Use the dilution formula to calculate the new concentration.

$\begin{array}{rcl}c_{1}V_{1} & = & c_{2}V_{2}\\0.01985 \times 10.00 & = & c_{2} \times 50.00\\0.1985 & = & 50.00 c_{2}\\\\c_{2}& = & \dfrac{0.1985}{50.00}\\\\& = & \text{0.003 970 mol/L}\\\end{array}$

B. Second dilution

Repeat Step 1, using the 0.003 970 mol·L⁻¹ solution.

$\begin{array}{rcl}c_{2}V_{2} & = & c_{3}V_{3}\\0.003970 \times 10.00 & = & c_{3} \times 50.00\\0.03970 & = & 50.00 c_{3}\\\\c_{3}& = & \dfrac{0.03970}{50.00}\\\\& = & \textbf{0.000 7940 mol/L}\\\end{array}\\\text{The concentration of the final solution is $\boxed{\textbf{0.000 7940 mol/L}}$}$

3. Check:

Compare the final concentration with the original

$\begin{array}{rcl}\dfrac{ c_{3}}{ c_{1}} & = & \dfrac{0.0007940}{0.01985}\\& = & \mathbf{\dfrac{1}{25.00}}\\\end{array}\\\text{The concentration of the final solution is } \boxed{\mathbf{\dfrac{1}{25}}} \text{ that of the original solution}$

Which of the following best describes your choice? It’s my best explanation for now, but I really would have to test my idea to

HACTEHA [7]

I can deduce here that the best that describes my choice is: It’s my best explanation for now, but I really would have to test my idea to be sure.

<h3>What is choice?</h3>

Choice actually refers to the act of choosing between two or more things. It has to do with going with the option, idea, decision, product or something that one prefers.

When we make choices, it depicts what we actually want. Some people still make wrong choices. The choices people make can either make or mar them in the present or future.

Looking at the given question, my choice is actually the first option.

It's clear that the idea hasn't been tested in order to be sure though it's has the best explanation.
