Question-8 : Ice is melting!!

There was a block of ice in an isolated container at temperature 0° C. We wanted to determine its mass, therefore we let some steam with a temperature of 100° C into the container, but we could not determine the exact amount or the steam. After re-closing the container all the ice melted, and the equilibrium temperature become 10° C. Then, once more we let some steam of temperature 100° C into the container, but again we could not determine its exact amount. The temperature in the container became 15° C. Finally, we let again some steam into the container, and this time we could determine it's mass, which was 0.3kg. The new equilibrium temperature in the container becomes 23° C. Determine the mass of the ice block.
