Given: t (water temperature before crystallization) = 0 ºС; Q (the amount of heat released during crystallization) = 34 kJ (34 * 10 ^ 3 J).
Constants: λ (specific heat of ice melting (water crystallization)) = 34 * 10 ^ 4 J / kg.
The mass of the ice formed can be calculated from the formula: Q = λ * m and m = Q / λ.
Calculation: m = 34 * 10 ^ 3 / (34 * 10 ^ 4) = 1/10 = 0.1 kg (100 g).
Answer: The mass of the formed ice is 100 grams.
