An ice cube has an initial temperature of −12.0 ∘C-12.0\ ^\circ\text{C}−12.0 ∘C. The total thermal energy required to raise the temperature of this ice cube to 0.0 ∘C0.0\ ^\circ\text{C}0.0 ∘C and completely melt it is 8980 J.

Given:

  • Specific heat capacity of ice = 2100 J/(kg ∘C)2100\text{ J/(kg }^\circ\text{C)}2100 J/(kg ∘C)
  • Specific latent heat of fusion of ice = 334 000 J/kg334\,000\text{ J/kg}334000 J/kg

Calculate the mass of the ice cube in kilograms.
