A 9.13 g sample of vanadium is heated to 99.10 °C and is then dropped into 20.0 grams of water in an insulated cup. The water temperature rises from 20.51 to 24.26 °C. Calculate the specific heat of the vanadium. All the possible information and still can't figure out how to find vanadium's specific heat as no amount of heat is given.
