serial dilutions are useful when
we want to obtain a very diluted solution from very concentrated stock solutions
direct dilution formula
M1V1 = M2V2
when performing a serial dilution
we first look at the final volume and concentrations needed, then determine the dilution factor
if we need 10 ml of a 1mM solution, out dilution factor is
Dilution factor = 1 / (final concentration / initial concentration) = 1 / (0.001M / 1M) = 1000X
When it is a 10X dilution
it means that it is 1 part of the solution, 9 parts of the diluent
