An ice cube has a temperature of -15.0 °C

The total thermal energy needed to raise the temperature of this ice cube to 0.0 °C and completely melt the ice cube is 5848 J

specific heat capacity of ice =2100J/kg°C

specific latent heat of fusion of ice = 334 000 J/kg
Calculate the mass of the ice cube.
