A solid silver coin (specific heat = 235 J/kg°C) is heated to a temperature of 58.0°C and added to 100 milliliters of 25.0°C water inside a calorimeter. If the water in the calorimeter reaches an equilibrium temperature of 27.0°C after the coin is added to it, what is the mass, in grams, of the silver coin?
