a stock room supervisor measured the contents of a partially filled 25 gallon acetone drum on a day when the temperature was 18°c and atmospheric pressure was 780mm Hg,and found that 15.4 gallons of the solvent remained. after tightly sealing the drum a student assistant dropped the drum while carrying it upstairs to the organic lab . the drum was dented and its internal volume was decreased to 20.4 gallon. what is the total pressure inside the drum after the accident? the vapour pressure of acetone at 18°c is 400mm Hg.
1It was dented so much that it's volume decreased by 5 gallons ( 10 litres ) !!!!!!!!!
Use PV = constant , add 400 mm to the final answer.
1there are a lot of p's and v's out there abhishek so can u tell which p and which v and what about the rest of the values
what was the reason for ur answer why should we add 400mm to final why can't we equate it with pv. i realy didn't undestand it. pls help
