A piece of copper of mass 300g at a temperature of 950 degrees Celsius is quickly transferred to a vessel containing 250g of water at 25 degrees Celsius. If the final steady temperature of the mixture is 100 degrees Celsius, calculate the mass of the water that will boil away. Given specific heat capacity of copper as 4.0 × 10² J/kg/K, specific heat capacity of water as 4.2 × 10³ J/kg/K, and latent heat of vaporization of steam as 2.26 × 10⁶ J/kg.
a) 97.4g
b) 113.8g
c) 125.2g
d) 137.6g
