11. If 0.0296 L of stock solution are diluted to 3.00L to form 0.345 M solution, what is the concentration of the stock solution?

Solutions

Expert Solution

be fore dilution                                            after dilution

M1 =                                                            M2 = 0.345M

V1 = 0.0296L                                               V2 = 3L

      M1V1    =   M2V2

      M1         = M2V2/V1

                   = 0.345*3/0.0296    = 34.96M >>>> answer
