To determine the specific heat of a new metal alloy, a 0.200-kg sample of the alloy is heated to 350°C and then placed in a 0.350-kg aluminum calorimeter cup containing 0.500 kg of water at 15.0°C. If the equilibrium temperature of the system is 32.8°C, what is the specific heat of the alloy? Express your answer in cal/g•C°. Note that, because you are given no information about the thermal properties of the thermometer and stirrer, their presence may be ignored.

3. To determine the specific heat of a new metal alloy, a 0.200-kg sample of the alloy is heated to
350°C and then placed in a 0.350-kg aluminum calorimeter cup containing 0.500 kg of water at
15.0°C. If the equilibrium temperature of the system is 32.8°C, what is the specific heat of the
alloy? Express your answer in cal/g•C°. Note that, because you are given no information about the
thermal properties of the thermometer and stirrer, their presence may be ignored.
