Specific heat problem finding final temp with calorimeter system

[bam09]

Homework Statement

A 34 g block of ice is cooled to -75°C. It is added to 562 g of water in an 80 g copper calorimeter at a temperature of 22°C. Find the final temperature. (The specific heat of copper is 387 J/kg ·°C and the specific heat of ice is 2090 J/kg ·°C. The latent heat of fusion of water 3.33 x 10^5 J/kg and the specific heat of water is 4186 J/kg ·°C.) Answer in units of °C.

Homework Equations

1,000 g= 1 kg

Q= mcdeltaT

Qice + Qlost H20 + Qcopper containter =0

mcdeltaT of ice + mL of ice + Qlost H20 + Qcopper container =0

The Attempt at a Solution

I tried the last equation.

.034(2090) (75) + (.034) (3.33e-9) + (.562)(4186)(Tf-22) + (.08)(387)(Ttf-22)=0

and i got 134.28 C which was wrong. Help!

Check the signs of the dT
which have heat flowing in and which out
