The Pressure Exerted by a Column of Liquid Is Equal

The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant times the density of the liquid, P = ghd. How high a column of methanol (d = 0.79 g/mL) would be supported by a pressure that supports a 713 mm column of mercury
(d = 13.6 g/mL) ?

A) 713 mm
B) 41 mm
C) 1.2 × 10⁴ mm
D) 9.7 × 10³ mm
E) 17 mm
