Homework Help: Chemistry

Posted by Kate on Tuesday, October 28, 2008 at 4:54pm.

I need help!
I found the change in Temp= -.9 degree C. I don't know what to do next...?

What value from this problem do I use as my q(heat capacity) to plug into the equation q= m X Cs X change T?

The question states:
120mL of H2O is intially @ room temp (22 degree C). A chilled steep rod @ 2 degree C is placed in the water. If the final temp of the system is 21.1 degree C, what is the mass of the rod?

Thank You!!!
