Use the concept of calorimetry where the colder water at 280°C absorbs the heat from the hotter water at 330°C
In this problem, we can just assume that water has a density of 1 g/mL which makes 30 mL and 50 mL pure water having a mass of 30 g and 50 g respectively
A 30.0 mL of pure water at 280. °C is mixed with 50.0 mL of pure water at 330. °C. What is the final temperature of the mixture (density of water = 1.00 g mL-1)?
A. 405 °C
B. 326 °C
C. 320. °C
D. 311 °C
E. 290. °C
