**DrBob222**, Friday, January 2, 2009 at 8:37pm[mass Cu x specific heat Cu x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0

Solve for specific heat Cu. It's easier to put in all the numbers first into the above, do the math, then solve for specific heat Cu last. Post your work if you get stuck. For your information, note the correct spelling of Celsius.

**GK**, Friday, January 2, 2009 at 8:41pmheat = (sp. heat)(grams)(temp. change)

or q = (C)(m)(Tf-Ti)

Heat released by Cu = Heat absorbed by H2O

(C)(46.2g)(95.4C-21.8C)= (4.18J/g.C)(75.0g)(21.8C-19.6C)

Solve for C to get the specific heat of copper.
