What other piece of information do you need to determine the amount of a chemical to add to 50 ml of dH2O to make a 10 mM solution?
One would add (give units) of NaOH to 100ml of dH2O to make a 40 mM solution.
One would add (give units) of water to 68mg of NaOH to make a 50 mM solution.
What would you do to make 10ml of 20mM NAD+ solution from a stock that is 80mM?
You have four tubes with 100 mM solutions of each of the four different deoxynucleotides (i. e. ATP, CTP, GTP, and TTP). How would you make 5 ml of a single solution that contains all four nucleotides at a 10 mM concentration?
Determine how to make 200 μl of a 1/600 serial dilution using two steps, a minimum of solvent (< 4 ml), and avoid sampling errors as much as possible (i. e. don’t use very small volumes).
