A small amount of water of mass m=50 g in a container at temperature T=273 K is placed inside a vacuum chamber which is evacuated rapidly. As a result, part of the water freezes and becomes ice and the rest becomes vapor.

The question is in the picture.

Extracted text: A small amount of water of mass m = 50 g in a container at temperature T = 273 K is placed inside a vacuum chamber which is evacuated rapidly. As a result, part of the water freezes and becomes ice and the rest becomes vapor. a) What amount of water initially transforms into ice? The latent heat of fusion (ice/water) q = (water/vapor) qv = 600 cal/g. b) A piece of heated metal alloy of mass M = 325 g and original volume V = 48 cm3 is placed inside the calorimeter together with the ice obtained as a result of the experiment in (a). The density of metal at T = 273 K is po = 6.8 g/cm³. The thermal capacity is C = 0.12 cal/g K, and the coefficient of linear expansion a = 1.1.10-5 K-1. How much ice will have melted when equilibrium is reached? 80 cal/g, and the latent heat of vaporization |3| %3D
