A piece of hot metal 120 °C is placed into a calorimeter that contains 40 ml of water at 22 °C After heat exchange is complete the temperature of water is 28 °C What is the mass of the metal? (Assume that no heat is lost to the surroundings). specific heat of metal: 0.126 °C specific heat of water: 4.184 J°C 121 density of water. 1 g ml

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

How to convert a density of 0.791g/cm3 to lb/ft3
