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 200 ml of PBS with 137mM NaCl, 2.7mM KCL and 8mM Na2HPO4and 2mM KH2PO4.solution. You’ve already added the Na2HPO4and theKH2PO4 (whew!) but you still need to add the NaCl and KCl from your stock solutions. Your stock solution of NaCl is 2M and the stock of KCl is 0.5M. How much NaCl and KCl do you need to add?

Suppose there is a McDonald's next to your school and you want to estimate the proportion, p of all people at your school who go to McDonald's on a typical school day. (a) If you had no preliminary estimate for p. how many people should you include in a random sample to be 85% sure that the estimate will be within a distance of 0.05 from p? Make sure to show the formula with the numbers plugged in. (b) Complete...
