William and Emma are conducting an experiment to find the specific heat of an unknown substance. They have 100.0 g of the substance at 200.0 °C, which reaches an equilibrium temperature of 27.1 °C when it comes in contact with a calorimeter of water. The water weighs 75.0 g and had an initial temperature of 20.00 °C. (Specific heat of water is 4.18 J/g°C) (show your work)

• 0.111 J/g°C

• 1.29 J/g°C

• 0.129 J/g°C

• 22225.85 J
