Define the final temperature of the coffee cup

Reference no: EM13665796

A student creates a coffee cup calorimeter for lab. The coffee cub contains 30mL of water at a temperature of 55.5 degrees Fahrenheit. He then adds 65.4mL of water, at 165.5 degrees Fahrenheit, into the coffee cup. The final temperature of the coffee cup is 120.3 degrees Fahrenheit. An Unknown amount of titanium (c = 25 mol^-1 C-1) is heated to 315 degrees Fahrenheit then added to the calorimeter containing 50g of water at 70 degrees Fahrenheit. The final temperature of the calorimeter is 150 degrees Fahrenheit. Explain what is the mass of titanium used? Explain the specific heat of water is 4.184
