"2.45J/g°C". To answer this question, we'll have to use this equation: q=mxxCxxDeltaT Where q is heat, m is mass in grams, C is specific heat capacity, and DeltaT is change in temperature. We can rearrange this equation to have C, which is what we want, alone on one side: C = q/(mxxDeltaT) The question already gives us q, m, and DeltaT, so we can just plug in these values and solve!
