You require a solution containing 127 mM of sodium hydroxide. You have 37 g of sodium hydroxide, how many mL of water do you need to add (whole number answer)?
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...
"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." 1. Explain why it is not necessary and even not desirable to perform the preparation of 1 M sodium hydroxide operation with higher accuracy. "Add the analyte to the beaker and fill with distilled deionized water to...
Explain why the 0.20 mol L -1 sodium hydroxide solution could not have been prepared by weighing out 2.00g sodium hydroxide, dissolving this in water and making up to 500 ml.
You need to prepare a 2.10 M solution of sodium hydroxide (molar mass of sodium hydroxide= 40.00 g/mol), but you only have 10 mL graduated cylinder and a 25 mL beaker. Complete the following sentences regarding the concentration of the prepared solution. 1. In order to prepare 10.0 mL (0.0100 L) solution of 2.10 M sodium hydroxide, a mass of ?? would be required. 2. When the solute and a total of 10.0 mL of water are both added into...
4) You have a 50 mM stock solution of sodium dodecylsulfate and you need to make 50 mL of a 0.1 mM solution. How much sodium dodecylsulfate will you need from the stock solution? 5) For Question #4, how much water will you need to add?
In an experiment, you need to create 275 mL of a 1M solution. You have 2L of a 5M stock solution. Calculate how much stock solution you would need to mix with water to make a 1M solution.You would take mL of the 5M stock solution in a flask and add mL of distilled water.Answers should be numerical (eg, 1, not one)
For the titration of 25.0 mL of 0.20 M hydrofluoric acid with 0.20 M sodium hydroxide, determine the volume of base added when pH is 3.15? (Ans: 12.5 ml) can you show the worked out solution?
if you have a 10 Malary sodium hydroxide solution, how could you prepare 50 mL of a three Malary sodium hydroxide solution? malary should say molarity
You need to neutralize a solution of an unknown concentration of sodium hydroxide before you can dispose of it. In the lab, you have a 5.0M bottle of hydrochloric acid, however, you want to dilute that first to use a less concentrated (and less dangerous) solution. So, you decide to use a 0.1M solution of hydrochloric acid solution and to make 2.0 litres of it. (a) Show all calculations for how you would do this. (b) Once you have your...
