When a 60.0 g sample of a metal at 100.0oC is added to 45.0 g of water at 22.00 oC, the final temperature of both the water and metal is 32.81 oC. The specific heat of water is 4.184 J/g·K. What is the specific heat of the metal?
1.) 33.9 J/g·K 2.) 0.339 J/g·K 3.) 0.505 J/g·K
4.) 0.199 J/g·K 5. none of these
