Ice at 10.0°C and steam at 130°C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 50.0°C is present. Ignoring the container and the equilibrium vapor pressure of the liquid at 50.0°C, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020 J/(kg · °C).
