We are trying to make 450 kg of 0.15 M NaOH solution by adding ice (-20 degC), 1.0 M NaOH aqueous solution at 25 degC and 0.10 M NaOH solution at 25 degC. We plan to use an adiabatic mixer, and apply 55 kJ of work for mixing thoroughly. Calculate how much of each should be added if we want to make the temperature of the final solution 25 degC.

You can solve it assuming density value
