Answer:
<h3>The answer is 0.49 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 2.34 g
density = 4.78 g/mL
We have
We have the final answer as
<h3>0.49 mL</h3>
Hope this helps you
Answer:
0.225M
Explanation:
Step 1:
Data obtained from the question. This includes:
Volume of the stock solution (V1) = 125mL
Molarity of the stock solution (M1) = 0.90 M
Volume of the diluted solution (V2) = 125 + 375 = 500mL
Molarity of the diluted solution (M2) =..?
Step 2:
Determination of the molarity of the diluted solution.
This is obtained by using the dilution formula as follow:
M1V1 = M2V2
0.9 x 125 = M2 x 500
Divide both side by 500
M2 = (0.9 x 125) /500
M2 = 0.225M
Therefore, the molarity of the diluted solution is 0.225M

A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided by the average of their peak widths is the definition of resolution.
Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.
The analyte's interaction with the stationary phase determines the longer retention period.
The duration of retention will increase as the interaction becomes more strong.
Resolution is defined as the peak separation in a chromatographic procedure that is equal to the difference in retention time for two components divided by the average of their peak widths.
