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.

HINT: What is the density of water?

ok, but now how do you find how much ice is needed? when density = mass/v and the density of water is 1000kg/m^3 =mass / 800mL

You first need to work out how much energy is required to change the temperature of 816 mL of water by 28oC.
