IV   Temp   COOH   RT   IV   Temp   COOH
start   start   start      End   End   End
[-]   [°C]   [MEQ/kg]   [min]   [--]   [°C]   [MEQ/kg]
0.6450   282.500   30.000   0.71   0.645   282.5   30.113

I want know how the COOH ended at 30.113 from start 30 MEQ/kg,
i need the calculation basis with formula to find out?
