In 1990, the average rate for use of fresh water in the United States was approximately 1.50 × 107 kg each second. Suppose a group of teenagers build a really big calorimeter and that they place in it a mass of water equal to the mass of fresh water consumed in 1.00 s. They then use a test sample of gold with a mass equal to that of the United States gold reserve for 1992. Initially, the gold has a temperature of 80.0°C and the water has a temperature of 1.00°C. If the final equilibrium temperature of the gold and water is 2.30°C, what is the mass of the gold?
