Height of Water in a Barometer Given Density & Column Height of Mercury – Chemistry Problems

This chemistry video tutorial explains how to calculate the height of water in a barometer given the density and column height of a mercury barometer. This tutorial explains how to derive the formula to calculate the column height of water using other equations in physics and geometry. The weight of the atmosphere must equal the weight of the fluid in the column for equilibrium to be established. Knowing this, you can derive the formula using density and the volume of a cylindrical prism.
