Thermochemistry- Specific heat capacity
« on: November 18, 2010, 08:41:30 PM »
 The question is: The specific heat capacity of copper is 0.385 J/g*K. How much energy is required to heat 168 g of copper from -12.2 degrees Celsius to +25.6 degrees Celcius?

i set up the problem as: q= (168)(0.385 J/g*K)(25.6-(-12.2)) and i got 2444.904 and doesn't seem right. What am i doing wrong?
