What pressure (atm) is exerted by a column of ethanol 86.0 cm high. The density of ethanol is 0.789 g/cm3 and 9.8 m/s2 as your gravitational constant.
pressure = density*acceleration gravity*height.
0.789g/cc x 86 cm x 980 cm/s^2 =?? Pa. Divide by 1000 to convert to kPa and divide by 101.325 to convert to atm.
