Given that the specific heat capacities of ice
and steam are 2.06 J/g ·
◦C and 2.03 J/g·
respectively, calculate the total quantity of
heat necessary to melt 23.5 g of ice at −50.0
◦C and heat it to steam at 200◦C. The molar
heats of fusion and vaporization for water are
6.02 kJ/mol and 40.6 kJ/mol, respectively.
Assume water freezes at 0◦C and boils at
Answer in units of J.
