**1. Homework Statement**

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. Homework 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.
