The problem below is informed:
Expression resolves to invalid units ('kg m^-3 s^-1') in value set for parameter 'Total Source' in object '/FLOW:Flow Analysi1/DOMAIN:serpentina/BOUNDARYut serpentina/BOUNDARY SOURCE/SOURCES/EQUATION SOURCE:C2H3Cl mvc.mf'. Expected units: 'kg s^-1'.
how could resolved this problem??

Your expression has the wrong units. You are giving it a concentration per second, and it is expecting a mass per second. Fix your expression so that it gives the expected units.

Now fred is in kg m^-3 s^-1
But even better - Erik's suggestion is that this means the expression calculating it is probably wrong. If the units do not check out the numbers have no hope of being right so dividing by m^-3 is not going to fix the real error.
