Noting that pressure is a force over a area (P=F/A, and the equation for gravitational force is F = m x g (where m is the masses of a person in kilograms and g=9.

A chemist is working on a reaction represented by this chemical equation: FeCl2 + 2KOH → Fe (OH) 2 + 2KCl. If the chemist uses 4.15 moles of iron (II) chloride and 3.
