Homework Statement
A 54.0 g ice cube, initially at 0°C, is dropped into a Styrofoam cup containing 327 g of water, initially at 19.4°C. What is the final temperature of the water, if no heat is transferred to the Styrofoam or the surroundings?
Homework Equations
Q=mc(delta)T
mc(delta)T+mc(delta)T = 0
Q=mL
Given- L=3.35e5
C(water) = 4190
The Attempt at a Solution
First i tried,
mc(delta)T+mc(delta)T = 0
.054kg*4190(T-0)+.327kg*4190(T-19.4)=0
then i tried...
mL+mc(delta)T+mc(delta)T = 0
(.054kg)(3.35e5)+.054kg*4190(T-0)+.327kg*4190(T-19.4)=0
both solve for Temp of course.
and both are wrong... help?!
