diluting solutions to prepare workable solution

-chemicals are shipped around the world in their most concentrated forms
-need to be able to make solutions of any concentration from a more concentrated source.

Ex: 2L 16.0 HCl I need 0.800L of 2.00M HCl

the key idea is that the moles of solute is constant (more water in less concentrated solute)
Formula: M1L1=M2L2
16M HCl x L1= 2.00M HCl x 0.800L=1.60moles
