Homework Statement
5.0 kg of ice at 0◦ is put into 3.0 kg of water at 20◦C. Assuming that they are isolated, that cH2O = 4186 J /kg K , and that L = 3.3 × 105 J/ kg how much ice is left when the system comes to equilibrium?
Homework Equations
Q= +/- mL
Q=mcΔT
The Attempt at a Solution
mLice+mcΔTwater=0
5(3.3×105)+3(T-293)(4186)=0
T=266.7K
This answer is clearly incorrect as it would give you a negative Celsius temperature. Also how would you find mass from this?
Any help would be much appreciated!
