Assume all temperatures to be exact. To determine the specific heat of a new metal alloy, 0.180 kg of the substance is heated to 440 °C  and then placed in a 0.150-kg aluminum calorimeter cup containing 0.430 kg of water at 18°C If the final temperature of the mixture is 42.5°C,what is the specific heat of the alloy? (Ignore the calorimeter stirrer and thermometer.)
