It tells us the number of protons that are present in the nucleus, the positively charged region of that atom.
Answer:c=0.213 J/g/K
Explanation:
Given
sample mass
initial temperature of mineral
mass of water
Water initial temperature
Heat capacity of calorimeter =15.3 J/k
Final Temperature is 24.8
let c be the specific heat of mineral
Heat released by mineral sample=heat absorbed by calorimeter and water
