Question

If 226 kJ of heat increases the temperature of 47.0 kg of copper by 12.5°C, what is the molar heat capacity of copper.​

Answer 1

Answer:

24.4 Jmol°C

Explanation:

Recall,

q=mCsΔT

Let's derive the specific heat, first,

⇒Cs=qmΔT≈0.385Jg⋅°C

and convert it to the molar heat capacity,

0.385Jg⋅C⋅

63.5gmol≈24.4Jmol⋅°C

which is the molar heat capacity of copper given your data.
