The total pressure in a flask containing air and ethanol at 25.7C is 878 mm Hg. The pressure of the air in the flask at 25.7C is 762 mm Hg. If the flask is immersed in a water bath at 30.0C, the total pressure is 980 mm Hg.The vapor pressure of ethanol at the new temperature is_________ mm Hg.
I think the problem is flawed. Do you have an answer that you KNOW is right?
