5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
The answer to this question would be: 0.385 j/g°c
Specific heat is the amount of energy needed to increase 1 degree of celcius per one gram of a specific mass. In this question, it needs 83.9 j/°c energy to increase the temperature of 218 g copper. Then, the specific heat would be: (83.9 j/°c) / 218g= 0.38486 j/g°c
