Okay so I believe this is a fairly straight forward enthalpy problem, but for what ever reason it says i'm wrong.
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 6.37 °C during the reaction. The specific heat of the reaction solution is known to be 6.20 J/g•°C, and the mass of the solution was measured as 33.0 g. Calculate q, the heat for this reaction, in kJ. Be sure to include the correct sign for your answer.
So here is what I did.
I understand the equation i'm to use is q=cm(change in temperature)= (specific heat of solution)(mass of solution)(change in temperature).
So by following this formula I got;
q=(33.0g)(6.20 J/ g centigrade)(6.37 centigrade)(1 kJ/ 1000 J) = 1.30 kJ
Did I miss something completely or is there an error in my conversions?
