chemist carefully measures the amount of heat needed to raise the temperature of a 442.0mg sample of a pure substance from 15.7°C to 24.7°C.?
The experiment shows that 9.7J of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 2 significant digits.?J x g^-1 x K^-1

Verified answer
C = Q/(m*delta T) = 9.7/((442*10^-3)*9) J/gK = 2.438 J/gK
