what are the molecular and empirical chemical formulas of a compound made up of these molecules?
the lines stand for chemical bonds between the atoms. you can ignore the dots -- they represent \lone pairs\ and youll
learn about them later.
molecular formula:
empirical formula:

Explanation:

Step1: Count atoms

Count the number of each type of atom in the molecule. There are 4 carbon (C) atoms, 8 hydrogen (H) atoms, and 2 oxygen (O) atoms. So the molecular formula is \(C_{4}H_{8}O_{2}\).

Step2: Simplify ratio

Find the simplest whole - number ratio of atoms. Divide the sub - scripts in the molecular formula by 2. The ratio of \(C:H:O = 2:4:1\). So the empirical formula is \(C_{2}H_{4}O\).

Answer:

molecular formula: \(C_{4}H_{8}O_{2}\)
empirical formula: \(C_{2}H_{4}O\)
