A metal container, which has a mass of 9.4 kg contains 14.2 kg of water. A 1.7-kg piece of the same metal, initially at a temperature of 160.0°C, is dropped into the water. The container and the water initially have a temperature of 15.0°C and the final temperature of the entire system is 17.0°C. Calculate the specific heat of the metal.
I got 124.73 but when I put units in it says it's wrong. What are the units? Please help. Units always confuse me.
