The specific heat of water and steam (water vapor) are 4.18
J/gºC and 2.10 J/gºC respectively. If 127 kJ of heat is need to
heat a 54.0 g sample of water from 74.20 °C to water vapor at
105.50 °C, what is the heat of vaporization of water in J/g?
Assume the boiling point of water is 100.00 °C.
_ J/g

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
