An unknown metal with mass 6.05 g is heated to 90.00°C and dropped into 11.0 g of water at 23.00°C. The final temperature of the system is 23.83°C. What is the specific heat of the metal? Assume the specific heat of water is 4.184 J/g oC. 

(Round to 3 decimal places and include units)

_______  _______ 

An insulated cup contains 75.0 g of water at 24.00 °C. A 26.00 g sample of metal at 85.25°C is added. The final temperature of the water and the metal is 28.34°C. What is the specific heat of the metal? Round to 3 decimal places. Assume the specific heat of water is 4.184 J/g°C.

 _______ _______ 

A piece of metal with a specific heat of 1.50 J/g°C is heated to 200°C then placed into a container with 150g of water at 20°C. The final temperature of the water and the metal is 30°C. Assume the specific heat of water is 4.184 J/g°C. Find the mass of the metal.
