use the procedures developed in this chapter to find the general solution of each differential equation.

Determining Molecular Formulas § Empirical formula § Accepted formula unit for ionic compounds § Molecular formula § Preferred for molecular compounds § In some cases molecular and empirical formulas are the same § When they are different, the subscripts of molecular formula are integer multiples of those in empirical formula § If empirical formula is AxBy § Molecular formula will be A n × x n × y Determining Molecular Formula § Need molecular mass and empirical formula § Calculate ratio of molecular mass to mass predicted by empirical formula and round to nearest integer molecular mass n = empirical formula mass Example: Glucose Molecular mass is 180.16 g/mol Empirical formula = CH O 2 Empirical fo
