**bobpursley**, Friday, May 6, 2011 at 6:44pmthe sum of heats gained is zero.

heatgainedicemelting+ heatgained by water heating+ heat gained alumin heating=0

.045*Hfice+(.045)specheatwater*(Tf-0)+.390*specheatwater*(Tf-34)+.150specheatAl(Tf-34)=0

solve for Tf

**Amy**, Saturday, May 7, 2011 at 10:17pmso i did

(0.45*333.55) + (0.045*4.816)(T-0) + (0.39*4.186)(T-34) + (.15*920)(T-34) = 0

15.009 + 0.18837T + 55.51-1.63254T + 4692 - 138T = 0

4762.519 - 139.4T = 0

T = 34.16 C

But I'm getting the wrong answer. Am I using the wrong number for Al? Or Hf?
