Calculate the Amount of Heat Energy in KJ Required to Convert

question 21

Short Answer

Calculate the amount of heat energy in kJ required to convert 45.0 g of ice at -15.5°C to steam at 124.0°C. (C_water = 4.18 J/g°C; C_ice = 2.03 J/g°C; C_steam = 2.02 J/g°C; molar heat of fusion of ice = 6.01 × 10³ J/mol; molar heat of vaporization of liquid water = 4.07 × 10⁴ J/mol)
