Some handy info: specific heat of ice = 2.1 J/gºC, specific heat of liquid water = 4.18 J/gºC, specific
heat of steam = 2.1J/gºC, heat of fusion/solidification of water = 334 J/g, heat of
vaporization/condensation of water = 2260 J/g
When a 10.8 g sample of solid sodium hydroxide dissolves in 100.0 g of water in a
Styrofoam cup, the temperature rises from 22.6°C to 41.8° C. Calculate AH in
kJ/mol for the solution process.
