An empty coffee-cup calorimeter weighs 10 grams. It is filled with water, whose temperature is 31 degrees Celsius, and is weighed again. The weighing scale displayed 55 grams. A metal sample is heated to 90 degrees Celsius and then placed into the coffee-cup calorimeter. The cover, with a thermometer, is quickly put on top of the calorimeter. The temperature reading on the thermometer stabilized at 33 degrees Celsius. The mass of the metal is 6.45 grams, Use 4.184 J/9•0C for the Specific heat of water. What is the specific heat in J/ g.0C of the metal sample?

Question

An experiment on determining the heat of combustion of propanol (C3H7OH) has the following results:

mass of water inside a can = 100 g

temperature of water before heating = 31°C

temperature of water after heating = 95°C

mass of propanol used = 20 g

Find the experimental standard enthalpy of combustion of propanol in kilojoules per mole. Use 4.184 J J/g∙0C for the specific heat of water.
