1. The problem statement, all variables and given/known data Ice at 0.0°C is mixed with 8 × 102 mL of water at 28°C. How much ice must melt to lower the water temperature to 0.0°C? 2. Relevant equations Q = mc(delta)T 3. The attempt at a solution c = 4.184 J/g K (delta)T = -28C V = 800 mL I'm not sure what to do since the volume is given and not the mass in this problem.
