During the crystallization of molten tin, an amount of heat of 29 kJ was released, which is the mass of tin.

These tasks: Q (heat released during crystallization of taken tin) = 29 kJ (29 * 10 ^ 3 J).

Constants: λ (specific heat of crystallization of tin) = 0.59 * 10 ^ 5 J / kg.

To determine the mass of crystallized tin, we use the formula: Q = λ * m, whence m = Q / λ.

Calculation: m = 29 * 10 ^ 3 / (0.59 * 10 ^ 5) = 0.4915 kg (491.5 g).

Answer: 4941.5 g of molten tin were taken.
