Question

A stockroom supervisor measured the contents of a 250 gallon drum partially filled with acetone on a day when the temperature was 18.0 °C and atmospheric pressure was 780 mm Hg, and found that 154 gallon of the solvent remained. After tightly sealing the drum, an assistant dropped the drum while carrying it upstairs to the organic laboratory. The drum was dented, and its internal volume was decreased to 204 gallon. What is the total pressure inside the drum after the accident? The vapour pressure of acetone at 18.0 °C is 400 mmHg. (Hint: At the time the drum was sealed, the pressure inside the drum, which is equal to the sum of the pressures of air and acetone, was equal to the atmospheric pressure.)
