Answer:

The height of a column of ethanol is 13.1m

Explanation:

we begin by converting the density to SI unit= 0.789g/cm3* 1kg * [tex]100^{3}[/tex]* [tex]cm^{3}[/tex]

                                                                               cm * 1000g * [tex]1^{3}m^{3}[/tex]

                                                            = 789kg/m3

converting pressure to SI unit= 1 atm =101325 Pa

hence P= hdg

g= 9.81 m/s2

making h the subject of the formula

h= P/dg

h= 101325Pa/ 789kg/m3 * 9.81 m/s2

h= 13.1m
