-5 2) In part 2 of the experiment, you are asked to prepare 5.0 mL of 2.0x 10 M FMN starting with a -4 -4 1.0 x 10 M solution of FMN? Calculate the amounts of 1.0 x 10 M FMN solution and water needed

Solution

Using the equation

M1V1 = M2V2

Let V2 is ml of FMN required and then water in the mixture is (5-V2) ml

M1, V1 = Molarity of FMN initially

M2 = 0.0001 M

0.00002 x 5 = 0.0001 x V2

V2 = 1 ml

FMN = 1 ml

Water = 5 -1 = 4 ml
