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 58 mL of 0.154 M Visine, considering that sea water has a concentration 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)
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...

During the weighing out process you weigh out 201.53 NaOH, what is your new molarity? Using your stock solution, you want to make a series of dilutions, you want 25 mL of the following concentrations of NaOH: 0.5 M ,1 M, 3 M, 7 M, 9 M. How much...
3. You're so thrilled by your geometric and designing capabilities (see problems 1 and 2) that you decide to design a thin dinner plate that on your blueprint covers the region between the r-axis and the curve To impress the friends, you decide to make two versions of the plate and exhibit them by holding them up on a single finger. In order to do this, you need to calculate the center of mass of each. (a) (5 points) One...
Anyone want to be a class hero? Our entire class is stuck and the professor isn't responsding (and its due soon). We can't figure out how to connect our four outputs of the multiplexers to a single four input decoder in a way that causes the two seven segment displays to alternate (see instructions). I understand the idea is that we set the clock to a very high frequency so it looks like they are both on when they are...
