If I'm given a solution containing sucrose (0.55 mol dm-3, 50cm3), and required to make a sucrose solution with a concentration of 3.2 x 10-2 mol dm-3, will I do that by changing the volume as follows?
C1 x V1 = C2 X V2
0.55 mol dm-3 x 0.05 dm-3 = 3.2 x 10-2 mol dm-3 x V2
V2 = 0.8594 dm-3
So, can we say that in order to make a sucrose solution with a concentration of 3.2 x 10-2 mol dm-3, we need V2-V2 dm-3? That is, 0.8594 dm-3 - 0.05 dm-3 = 0.8094 dm-3?
