Actually, you decide that you want to make visine by diluting sea water. You can't see any problems with your brilliant idea How many mL of sea water do you need to make 33 ml of 0.154 M "Visine," considering that sea water has a concentratio of 0.600 M? Give your answer in milliliters to two digits past the decimal, and DO NOT include units.
You want to make a bottle of Visine, against the recommendations of your chemistry professor. Knowing that Visine is lly just a 0.154 M NaCl solution, you decide to make a 239 ml bottle of the stuff. How many moles of NaCl do you need? Give your answer in moles to four digits past the decimal, and DO NOT include units.
A stock solution of 5 M sodium acetate has been made. You want to make a 50 ml 0.33 M sodium acetate solution for your lab bench. How much of the stock solution and water do you need? (ml)
Questions 1. Why do you want to stop the titration of want to stop the titration of the solution at the lightest pink color you can detect? Because it's the equvilant point 2. How would this experiment change if the HCI was the standard solution and NaOH was the unknown? 3. What is the proper way to dilute acids with water? water then acid 4. In this experiment, you diluted the HCI given to you and then titrated the samples....
A. You have been given a tube of E. coli. You are asked to make 1 mL total volume of 10-1 dilution of the bacterial culture. Explain how you would do this. Show all necessary calculations. ____ ml cells + _____ ml water = 1 ml (total volume) B. Next, you were asked to make a 10-2 dilution of the bacterial sample. Explain how you would perform this. Show all necessary calculations. You have bacteria at a concentration of 2...
You want to determine the concentration of acid in a particular solution. To this end, you decide to titrate the acid with a standardized sodium hydroxide solution. You quickly throw together an approximately 0.1 M NaOH solution, and then you realize you need to know the exact concentration of this solution before you can use it for anything meaningful. 1. Using an acid-base titration, 30.65 mL of your NaOH solution were needed to neutralize 0.6923 g of KHP (potassium hydrogen...
3. You dissolve the sample of FD&C Red 40 in enough water to make 250.0 mL of solution. We call this the stock solution What is the concentration of the stock solution in terms of molarity? 8.7x10-5 M You are correct. Your receipt no. is 156-2105 4. You make two dilutions. You take 87.60 mL of the stock solution and dilute to 500.0 mL to make Solution #1. You then add 65.28 mL of Solution 1 to 37.34 mL of...
candida glabrata info, any info about it just do the graph and explain this Results You will actually want to decide what you intend to show in your results before you work through your materials and methods. You have to first ask yourself, "What am I trying to prove?" before you can work out, Here's how I'm going to go about proving it." You will need at least two graphs for your results, which means that you need at least...
4 points Suppose you want to make a 0.6 M FeCl3 (molar mass = 162.2 g/mol) solution. If you have 1.01 grams of iron (III) chloride, what volume (in mL) of water will you need to make the 0.6 M solution? * Your answer
It's Saturday night and you and your friend Tabitha decide to go see a movie. As you are waiting in line you notice a bunch of rowdy teenagers buying tickets to see the same movie as you. You suggest to Tabitha that you see another movie because you anticipate that the teenagers will be noisy and prevent you from fully enjoying the movie. Tabitha has been excited to see that particular movie all week and says no, she doesn't want...
