Homework Help: Chemistry

Posted by Joe on Wednesday, January 30, 2013 at 1:39pm.

You carry out an exothermic reaction inside a Styrofoam cup calorimeter, using a temperature probe to monitor the temperature throughout the reaction. You find that the temperature increases 7.40 C during the reaction. The specific heat of the reaction solution is known to be 5.59 J/gC, and the mass of the solution was measured as 36.0 g. Calculate q, the heat for this reaction, in kJ. Be sure to include the correct sign for your answer.

What I did was the following;

q=(5.59 J/gC)(36.0g)(7.40)(1 kJ/ 1000 J) =1.49 kJ

however the program I am working with says I'm wrong.
