Answer:
30.63 °C will be the final temperature of the water.
Explanation:
Heat lost by iron will be equal to heat gained by the water

Mass of iron = 
Specific heat capacity of iron = 
Initial temperature of the iron = 
Final temperature =
=T

Volume of water = 300 ml
Density of water = 1 g/mL
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
=T



On substituting all values:
we get, T = 30.63°C
30.63 °C will be the final temperature of the water.
