During the crystallization of molten tin, an amount of heat of 29 kJ was released. What is the mass of tin?
| June 30, 2021 | education
Data: Q (heat obtained due to crystallization of taken tin) = 29 kJ = 29 * 10 ^ 3 J; λ (specific heat of crystallization of tin) = 5.9 * 10 ^ 4 J / kg.
Tin mass taken: m = Q / λ = 29 * 10 ^ 3 / (5.9 * 10 ^ 4) = 0.492 kg.
Answer: The mass of crystallized tin is 492 grams.
