Answer:
0.17 J/g*C
Step-by-step explanation:
Specific heat capacity will have units of heat per unit mass, per degree temperature. Using the units provided here, we would expect to find a specific heat expressed as J/(g*C). This can be read as the energy required to raise 1 gram of the material 1 degree C. Or it can be read as the amount of energy that needs to be removed to reduce the temperature of 1 gram of material by 1 degree C.
We are given the three values needed to determine specific heat capacity. Just piut them together in a manner that will result in the correct unit: J/(g*C).
160 J released
5.0 g metal
A temperature change of (225-35) or 190C.
We want J/(g*C)
160J/(5.0g*190C) = 0.1684 J/g*C or 0.17 J/g*C for 2 sig figs
