Question
Chapter 7, Problem 83APP
Interpretation Introduction
Interpretation : The empirical and molecular formula of the compound should be calculated.
Concept Introduction : Any compound can easily represent with the help of molecular formula. Another type of formula is empirical formula which represents the lowest whole number ratio of atoms in a compound. It does not represent the actual number of atoms in the molecule. The relation between molecular formula and empirical formula can be written as;
Molecular formula = small integer x empirical formula
The following steps should be followed to get the molecular formula:
1. Calculate the number of moles for each element.
2. Divide by smallest number of moles.
3. Write the empirical formula with the help of whole number of step-2.
4. Calculate the mass of empirical formula with the help of
5. Calculate the integer value and find the molecular formula.
