A 25.00 cm^3 block of osmium with a temperature of 3000.0 degrees Celsius is placed in 10.545 L of 1,2-ethanediol at 25.00 degrees Celsius. What is osmium's molar capacity if the two substances reach thermal equilibrium at 100 degrees Celsius? Osmium, the densest known metal, has a density of 22.57 g/cm^3. 1,2-ethanediol, HOC2H4OH (aka ethylene glycol) is the primary ingredient in automobile "anti-freeze" solutions. 1,2-ethanediol has a density of 1.1088g/cm^3 and a Cp=2.42J/g*K.
