Thermodynamics - again, Part of the ice that melt :S

[Planck const]

Homework Statement

Stamp of iron the his mass - M and temp' - T0 (T0>100 C deg') has been placed on cube of ice.

The mass of the ice - m, the temp' - t0 = 0 C deg'


How many present of the ice get melt?

Homework Equations

Q = mc$\Delta$t

The Attempt at a Solution

If I let all the ice getting melt, I got one equation with one unknown size - T (end)

But if I define constant K that representative the presents of the ice that melt... I got two unknown sizes - K and T (end)

What I supposed to do?!

Thanks in advance!

Without actual numbers to put in the variables there are a number of different outcomes possible. Perhaps you are expected to identify and show formulas for all of the possibilities?
