The motor heat capacity of rock salt at ...

The motor heat capacity of rock salt at low temperatures varies with temperatures according to Debye's `T_(3)` law.
Thus, C = `kT^(3)/theta^(3)`, where k = 1940 J`mol^(-1)Ko^(-1)`, `theta` = 281 K)
Calculate how much heat is required to raise the tempratures of 2 moles of rock salt from 10 K to 50 K?
