A researcher studying the nutritional value of a new candy places a 3.70 g sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.86 ∘C. If the heat capacity of the calorimeter is 29.50 kJ⋅K−1, how many nutritional Calories are there per gram of the candy? Calories per gram of candy

A 6.78 g sample of methanol was combusted in a bomb calorimeter. The temperature of the calorimeter increased by 12.7 °C. If the molar mass of methanol is 32.04 g/mol, and the heat capacity of the calorimeter is 5,104 J/°C, what is the molar AE for this reaction, in kJ/mol? Do not report units in your answer. Report your answer to one decimal place and include the correct sign.

A 21.7 g piece of iron and a 28.6 g piece of gold at 100.0°C were dropped into 770.0 mL of water at 25.0°C. The molar heat capacities of iron and gold are 25.19 J/(mol·°C) and 25.41 J/(mol·°C), respectively. What is the final temperature of the water and pieces of metal?

An experiment was conducted to determine the specific heat of platinum.  It was determined that 158.8 Joules of heat were required to increase the temperature of a 50.0 gram sample of platinum from 20.0 oC to 45.5 oC.  Based on these experimental results calculate the specific heat (J/g⋅⋅oC) of platinum.
