If 2.00 m3 of water at 0°C is frozen and cooled to -25°C by being in contact with a great deal of ice at -25°C, what would be the total change in entropy of the process?

2. Relevant equations

ΔS=Q/T Q=mL Q=mcΔT

3. The attempt at a solution

2000 * 4190 * ln (273/(273-25) + 2000* 336000/273 = 265854.8 J/K

Why is natural log being used?
