The simplest (or empirical) formula of the compound expresses that ratio. Simplest formulas are determined by establishing the mass of each element present in a sample of the compound. From those masses one finds the number of moles of each element present. The mole ratio is also the atom ratio in the compound and that ratio provides the subscripts

Assignments Requirements 1. Look up the definition of functional dependency. Can you find a good example? In relational database theory‚ a functional dependency is a constraint between two sets of attributes in a relation from a database. Cars Suppose one is designing a system to track vehicles and the capacity of their engines. Each vehicle has a unique vehicle identification number (VIN). One would write VIN → Engine Capacity because it would be inappropriate for a vehicle’s engine to have
