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 have seen that others have posted the same problem, but it seems that the answer i plug in is wrong.
