The heat capacity required to raise the temperature of 9.4 mole of water from 75.0oC to 125oC at atmospheric pressure is 35429 J.
The following information is available from the question;
Number of moles = 9.4 mole
Initial temperature = 75.0oC
Final temperature = 125oC
Molar heat capacity = 75.38 J/mol °C
Now;
H = ncθ
m = Number of moles of water
c = Molar heat capacity of water
θ = Temperature rise
Substituting values;
H = 9.4 mole × 75.38 J/mol °C × ( 125oC - 75.0oC)
H = 35429 J
