An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10°C. Two metallic blocks are placed into the water. One is a 47.9-g piece of silver at 80°C. The other has a mass of 345 g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20°C.   (a) Determine the specific heat of the unknown sample.
