u din provide the following:
(i) specific heat capacity of water
(ii) specific heat capacity of ice
(iii) specific latent heat of fusion of water
i m assuming my set of values,
so may be a slight difference from the qn
heat lost
= 1 x 4200 x 20
= 84 000
heat gain
= M x 2100 x 20 + (M-m) x 336 000
= 378 000 M - 336 000 m
84 000
= 378 000 M - 336 000 m
m = 1.125 M - 0.25

Updated. Credit to Snell for pointing out my error.
Qwerty, you should use the values for the specific heat capacity and specific latent heat provided by your teacher or the syllabus (if the syllabus does quote them).
