Expert Solution
Step 1
Given that,
The mass of ice (H2O) is 84.5 g.
We have to calculate the heat required to bring it to a temperature of 11.1 0C.
Therefore, we have to required amount of heat to melt ice as well as increase temperature from it's melting point ( 0 0C) to 11.1 0C.
The standard data of ice is as:
Melting point = 0 0C
Heat capacity of ice (S) = 2100 J kg−1 0C−1
Enthalpy of fusion for ice = 6.02 kJ/mol
Total heat required = Heat for melting (Q1) + Heat to increase temperature (Q2)
