B. if you want to make 50 ml of a 1x TAE solution from a 50X stock, how would you prepare it?
C. If you have 1.0 x 10 ^9 molecules in a tube and perform a 10^-7 dilution, how many molecules will be in the new tube?
D. If you have 50 molecules in a 10^-5 dilution, how many molecules were in the original solution?
E.If you have 375 molecules in a 10^-4 dilution, how many molecules were in the original solution?
F. If you diluted a solution of molecules by putting 300 ul into 2.7 ml of water, mixing and taking 300 ul from this dilution into another 2.7 ml of water, what is the dilution of the final tube?
