Suppose that only two 45-g ice cubes had been added to your glass containing 5.00 × 10² mL of tea. When thermal equilibrium is reached, all of the ice will have melted, and the temperature of the mixture will be somewhere between 20.0°C and 0°C. Calculate the final temperature of the beverage. The 90 g of water formed when the ice melts must be warmed from 0°C to the final temperature.
