Given:
Concentration 1 = 100.0 ml Concentration 2 = ?
Volume 1 = 0.100 M KCL Volume 2= 0.500 M KCL
Find Concentration 2
To get the concentration 2, follow this formula
C1V1 = C2V2
Solution
(100.0 ml) (0.100 m kcl) = (X ml) (0.500 m kcl)
transfer the volume 2 to the left side
(100.0 ml) (0.100 m kcl) = X ml
---------------------------------
0.500 m kcl
10.00ml / m kcl = Xml
-------------------- cancel the m kcl to let the ml be the remaining variable
0.500 m kcl
20.0 ml = x ml
So you will need 20.0 ml of 0.500 m kcl to made the solution of 100.0 ml of 0.100 m kcl
