(i) the volume of sodium hydroxide taken = 2mL = V1 concentration = 4M = M1
final volume = V2 = 100mL concentration = M2
Therefore
M1V1 = M2V2
M2 = 2 X 4 / 100= 0.08 M
2) the volume of sodium hydroxide taken = 4mL = V1 concentration = 4M = M1
final volume = V2 = 100mL concentration = M2
Therefore
M1V1 = M2V2
M2 = 4 X 4 / 100= 0.16 M
3) the volume of sodium hydroxide taken = 6mL = V1 concentration = 4M = M1
final volume = V2 = 100mL concentration = M2
Therefore
M1V1 = M2V2
M2 = 6 X 4 / 100= 0.24 M
4) the volume of sodium hydroxide taken = 8mL = V1 concentration = 4M = M1
final volume = V2 = 100mL concentration = M2
Therefore
M1V1 = M2V2
M2 = 8 X 4 / 100= 0.32 M
5) the volume of sodium hydroxide taken = 10mL = V1 concentration = 4M = M1
final volume = V2 = 100mL concentration = M2
Therefore
M1V1 = M2V2
M2 = 10 X 4 / 100= 0.4 M

A pipet is used to transfer 10.00 mL of a 4.00 M stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 1.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”

A chemist must prepare 750.0 mL of sodium hydroxide solution with a pH of 13.70 at 25 °C. She will do this in three steps: • Fill a 750.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid sodium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step. Round...

Question 1 2 pts 3.34 mL of an unknown glucose solution was diluted in a 100.00 mL of volumetric flask with distilled water. 10mL of that solution and 4.00 mL of the ferricyanide reagent was placed in a second 100.00 mL volumetric flask and diluted to the mark with distilled water. Spectrophotometric analysis of the glucose/ferricyanide solution showed that the concentration of glucose was 0.070 M. What is the concentration of glucose in the unknown solution?

Preparation of Sodium Hydroxide Titrant: Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask. Store the diluted solution in a polyethylene bottle. Standardize the diluted solution against dry, solid KHP (potassium hydrogen phthalate) using phenolphthalein as an indicator and label the bottle with the concentration of...
