what is the final temperature of amixture containning 25 grams of ice at 20 degree celciusadded to water at room temperature 22oC mass of water is 50g

Below are four stages:
1. heat needed to raise T ice @ 20C to zero C.
2. heat needed to melt ice at zero to liquid water at zero.
3. heat needed to raise T ice at zero C to final T.
4. heat lost by 20 degree water to final T.
[mass ice @ 20 x specific heat solid ice x (TfinalTinitial)] + [mass ice @ zero C x heat fusion] + [mass melted ice at zero x specific heat water x (TfinalTinitial)] + [mass warm water x specific heat water x (TfinalTinitial) = 0
