Expert Solution
Step 1

Given information,

Mass of sample (m) = 143 g 

Initial temperature (T1) = 100°C 

Final temperature (T2) = 0°C 

Change in temperature (∆T) = T2 - T1 = 0°C - 100°C = -100°C 

∆Hfus = 334 J/g

∆Hvap = 2260 J/g

Additional information,

Specific heat capacity of liquid water (c) = 4.18 J/g °C
