The total pressure in a flask containing air and ethanol at 257C is 878 mm Hg. The pressure of
the air in the flask at 257C is 762 mm Hg. If the flask is immersed in a water bath at 450C, the
total pressure is 980 mm Hg. The vapor pressure of ethanol at the new temperature is _____ mm Hg.


I really don't know what to do..i drew a picture but theres just so much info i cant seem to focus on what i need to find.
