The rule that we will use to solve this problem is: M2*V1 = M2*V2 where: M1 is the initial concentration = 3.5 m V1 is the initial volume = 0.25 l = 250 ml M2 is the final concentration = 9 m V2 is the final volume that we need to find
Substitute with the givens in the above equation to get V2 as follows: 3.5*250 = 9*V2 V2 = 97.2223 ml
