Question

The dilution formula can be used to to find the new concentration when a known amount and concentration of a solution is diluted to a known volume.

M1V1 = M2V2 where

M1 = concentrated solution
V1 = volume transferred (preferred unit is Liters)
M2 = new concentration of the diluted solution
V2 = total volume of the diluted solution (preferred unit is liters)

25.00mLs of a solution with an unknown molarity was transferred to a 500mL volumetric flask and diluted to volume with water. The solution was analyzed and the diluted concentration was found to be 0.300M. What was the concentration of the original solution? 

Provide step by step.
