You need to make 400 mL of a 0.20 M NaCl solution. If only a 1.0 M NaCl solution is available, explain how to make the needed dilution. How would you prepare 100 mL of a 2.2 M NaCl solution from a stock 6 M NaCl solution? Describe how you would prepare 500.0 ml of 0.400 M NaCl...
Related to this Question How many mL of 5 M NaCl are required to prepare 1500 mL of 0.002 M NaCl? If you have 200 mL of a 2.5 M NaCl solution, how many mL of a 0.25 M NaCl solution can you make? How many mL of a 2.0 M NaCl solution would you need to mak...
In order to make 100 mL of a 17% sodium azide solution, you would need to weigh out 17 grams of sodium azide and then add water until the final volume is 100 mL. You can make use of this equation in another way. Say you're told that the solution you will be using has 45 grams...
Example: Suppose you have 3 ml of a stock solution of 100 mg/ml ampicillin (= C1) and you want to make 200 ul (= V2)of solution having 25 mg/ ml (= C2). You need to know what volume (V1) of the stock to use as part of the 200 ul total volume needed. V1 = the volume...

Such a solution is usually prepared by diluting the HCl from a stock solution. Purchased concentrated HCl is usually 12.1 M. The question does not state how much acid to prepare so I will answer how to make one liter of 0.5 M HCl. ...
When making a solution, it's handy to know if one thing will dissolve in another. After all, if somebody wants you to make them a liquid solution of one chemical, it won't make you look good if you bring them a beaker of liquid with sludge sitting at the bottom because you chose ...
Now, you can tackle the question at the beginning of the article. Say you need to make 1 L of a 1M NaCl solution. How do you know how much salt to weight out? First, you will need to find the number of moles you need for this solution. To do this, you will need to make use...
... Neutral anolytes have a pH of 5.0 to 8.5 and redox of 700 to 900. How do you make hypochlorous acid? The chemistry behind making Hypochlorous is well-known: an electrolytic process breaks a saltwater solution (H2O + NaCl) down into essential elements before the reaction oxidises at ...
Kosher salt is used to make meats kosher by quickly drawing out the blood. Many chefs prefer to use kosher salt. Its coarse texture makes it easy to pick up and sprinkle on food during or after cooking. However, it doesn't dissolve as quickly as table salt, so it's better to use a...
