You devise an experiment to use the condensation of acetone vapor (58.1 g/mol,boiling point 56°C) to provide enough thermal energy to heat 0.180 kilograms of water at 56.0°C to steam at 100.0°C.About how many grams of acetone vapor at 56.0°C would be required? [acetone $\Delta$ H_vap = 31.3 kJ/mol; water $\Delta$ H_vap = 40.7 kJ/mol; c_p(water) = 4.18 J/(g.°C) ;
C_p(acetone vapor) = 1.29 J/(g.°C) ]

Quizplus · Accepted Answer

To solve this, calculate the energy needed to heat water from 56°C to 100°C and then vaporize it. Then, calculate the energy released by condensing acetone vapor. Equate the two to find the mass of acetone needed.
