Question

Calculate the amount of heat needed to melt 96.1 g of ice (H20) and bring it to a temperature of 68.6 degrees Celsius. Round your answer to 3 significant digits. Also, be sure that your answer contains a unit symbol.

Answer 1

heat to melt 96.1 g ice at 0ºC = 96.1 g x 334 J/g = 32,097 J

heat to raise temp of 96.1 g liquid water to 68.6ºC = 96.1 g x 4.184 J/g/deg x 68.6 deg = 27,583 J

Total joules needed = 32,097 J + 27,583 J = 59,680 J = 59.7 kJ (3 sig figs and units are kilo joules)
