### How much heat is required to heat 28.0 grams of solid ice at -20.0°C to liquid water at 98.0°C?

Use the appropriate data from below for the calculation.

- **Specific heat capacity of water, \( C_s, \text{water} \) = 4.184 J/g·°C**
- **Specific heat capacity of steam, \( C_s, \text{steam} \) = 2.01 J/g·°C**
- **Specific heat capacity of ice, \( C_s, \text{ice} \) = 2.09 J/g·°C**
- **Heat of fusion, \( H_\text{fusion} \) = 6.02 kJ/mol**
- **Heat of vaporization, \( H_\text{vaporization} \) = 40.7 kJ/mol**
- **Melting point of \( H_2O \) = 0°C**
- **Boiling point of \( H_2O \) = 100°C**

Options:
- 21.2 kJ
- 22.0 kJ
- 12.7 kJ
- 26.1 kJ
