Solutions

Expert Solution

Before dilution                                                      After dilution

M1 = 3M                                                               M2 = 0.6M

V1 =                                                                      V2 = 125ml

       M1V1   =   M2V2

        V1       =    M2V2/M1

                   = 0.6*125/3   = 25 ml >>>>>>answer

How many grams of CaCl2 should be added to 50.0 g of water to make a solution in which the mole fraction of Cl1- is 0.150? ***I understand how this question should be set up, I am confused about a certain part of the set up. The correct set up is as follows: 0.150 = (2n mol Cl-)/ (3n mol ions + 2.78 mol of H2O) and solve for n; I do not understand why the ratio within the problem...
