Answer:

300 kJ  

Explanation:

There are two energy flows in this process.

Heat lost by iron + heat gained by water =      0

            q₁             +                    q₂              =      0

       -300 kJ        +                     q₂              =      0  

                                                   q₂              = 300 kJ  

The water gained 300 kJ.
