Exercise $1(50$ points$)$

is filled with a height of $0\mathrm{.}5$ m of liquid water

of $1,000k\frac{g}{m^3})$ and $1$ m high layer of gasoline,

dailed in the figure below. The gasoline surface is exposed to

atmospheric air at $101$ kPa $.$ The highest pressure in the water is

$113\mathrm{.}2$ kPa $.$ Calculate the density of the gasoline.
