The required solution is prepared taking 0.1 mL of 10 M stock NaOH solution and placing it into a 100 mL volumetric flask. The solution is made up to 100 mL with distilled water in order to have a 100 mL solution of 10 mM NaOH solution.
The required solution is prepared by diluting a given volume of the stock solution.
Using the dilution formula: C₁V₁ = C₂V₂
Where C₁ = initial concentration of solution
V₁ = initial volume of solution
C₂ = final concentration of solution
V₂ = final volume of solution
From the given values:
C₁ = 10 M, V₁ = ?, C₂ = 10 mM = 0.01 M, V₂ = 100ml
Making V₁ subject of the formula in the dilution formula:
V₁ = C₂V₂/C₁
V₁ = 0.01 * 100 / 10
V₁ = 0.1 mL
Therefore, the volume of stock solution needed to prepare 100 mL of 10 mM NaOH solution is 0.1 mL.
0.1 mL of 10 M stock NaOH solution is taken and put into a 100 mL volumetric flask. The solution is made up to 100 mL with distilled water in order to have a 100 mL solution of 10 mM NaOH solution.

B all objects move around the sun
Answer:
Average temperatures in July range from 85°F to 90°F during the day but cool off quickly after dark, dropping into the 50s and 60s (°F). Some regions of Wyoming are classified as desert, so there isn't much precipitation. Most of it falls as rain in the late spring and early summer, which is also a windy time of year.
Explanation:idk if this helps awnser ur question
Answer:
Avogadro's number is 1 mol = 6.02 * 10^23 elements
It means that 1 mol of atoms is 6.02 * 10^23 atoms
1 mol of atoms = 6.02 * 10^23 atoms
From there, if you divide both sides by 1 mol of atoms, you get
1 = 6.02 * 10^23 atoms / 1 mol of atoms.
That means, that to pass from a number of moles of atoms to number of atoms you have to multipby by the conversion factor
6.02*10^23 atoms Al/ 1 mol Al
That is the second option of the list.
