2. A 35 g metal ball made up of a mixture of element X and element Y is heated up to 77°C and dropped into 20 mL of 15°C water. If the final temperature of the metal ball is 30°C, what percentage of the ball is made up of element X? The specific heat of element X is 0.46 J/g°C and the specific heat of element Y is (0.209 J/g"C).
