A prоfessоr likes his cоffee аt exаctly 45.0oC. To reduce the temperаture of a fresh cup of coffee (150.0g at 85.0 °C) quickly, the professor plans to place a pre-chilled silver spoon (4.0 °C) in the coffee and the two is allowed to reach the same temperature of 45.0oC. Assume that no heat is lost or gained from environment (air and cup), what must be the mass of the silver spoon (in grams)? Assume that the coffee has the same specific heat capacity as water, 4.184 J/(g oC). Specific heat capacity of silver is 0.235 J/(g °C). The professor may or may not be able to afford to buy such a silver spoon. Mark your answer next to words "Final answer is". You must follow significant figure rules.
