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 425C, the total pressure is 980 mm Hg. The vapor pressure of ethanol at the new temperature is ________mm Hg.
Hint: you will need to correct the pressure of air at the new temperature using the Gas Law: P1T1 = P2T2

yo yo yo I got
175.1637945 b/c :
p1/t1 = p2/t2
762/298.85 = p2/ 315.65
p2 = 804.8362055
subtract w/ 980.... get the positive value....
your welcome. hahaha UCI!!!!
