Specific Heat Capacities - Chemistry?

The specific heat capacities of hafnium and ethanol are 0.146 J/g*K and 2.45 J/g*K respectively. A piece of hot hafnium weighing 15.6 g at a temperature of 160.0 degrees celsius is dropped into 125 g of ethanol that has an initial temperature of 20.0 degrees celsius. What is the final temperature that is reached, uming no heat loss to surroundings?
