Change in entropy when ice melts to water at 0°C

[logearav]

Homework Statement

What is the change in entropy when 1 gm of ice at 0° C is converted into water at the same temperature?

Homework Equations

3. The attempt at the solution
dS = dQ/T.
Q = msT/T
so dS = 1*?*273/273
i don't know whether i should substitute specific heat capacity of water or specific heat capacity of ice at ?.
I also don't know whether my substitutions are correct. Revered members can help in this regard

You need to use the latent heat of fusion/melting for water.
