A sample of solid sulfur has an initial temperature of 25.0 ∘C25.0\ ^\circ\text{C}25.0 ∘C. The total thermal energy required to raise the temperature of this sample to its melting point of 115.0 ∘C115.0\ ^\circ\text{C}115.0 ∘C and completely melt it is 54.45 kJ54.45\text{ kJ}54.45 kJ.

Given:

  • Specific heat capacity of solid sulfur = 710 J/(kg ∘C)710\text{ J/(kg }^\circ\text{C)}710 J/(kg ∘C)
  • Specific latent heat of fusion of sulfur = 4.50×104 J/kg4.50 \times 10^4\text{ J/kg}4.50×104 J/kg

Calculate the mass of the sulfur sample in kilograms.
