You Devise an Experiment to Use the Condensation of Acetone $\Delta$

question 112

Multiple Choice

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) ]

• A)440 g
• B)581 g
• C)817 g
• D)75.5 g
• E)61.4 g
