2) coefficients have to be whole numbers
In addition, if you were to think about it, using fractions will take up more time and the process will be longer.

Question on Self Test G.3A
In the book, the questions asks "What volume of 1.25 x 10^-3 M C6H12O6 (aq) contains 1.44 umol (micro) of glucose molecules?" I am unsure how to change umol into mmmol. Can someone please explain these steps?
