Describe how a 250.0 mL aqueous solution of 1.50 M MgCl2 is prepared from a stock solution of 6.00 M MgCl2.
ANSWER: Measure 62.5 mL of the stock solution into a container and dilute to 250.0 mL
so what i need explained is where did 62.5 mL come from?
where M1=1.50 M, V1=250.0 mL, and M2=6.00M
just divide the 250mL by 4 to get 62.5, that cuts the molarity by 4 as well
