What is the molecular mass of ozone, O3? Atomic Mass Symbol (kg/mol) 0.0160 Element Oxygen (Unit = kg/mol)
The Correct Answer and Explanation is:
The molecular mass of ozone (O₃) can be calculated by summing the atomic masses of the oxygen atoms that make up the molecule. Ozone consists of three oxygen atoms, and since the atomic mass of oxygen is given as 0.0160 kg/mol, we can calculate the molecular mass as follows:
Step 1: The molecular formula of ozone is O₃, meaning it contains three oxygen atoms.
Step 2: The atomic mass of one oxygen atom is 0.0160 kg/mol.
Step 3: To find the molecular mass of ozone, multiply the atomic mass of one oxygen atom by the number of atoms in the molecule:Molecular mass of O₃=3×0.0160 kg/mol\text{Molecular mass of O₃} = 3 \times 0.0160 \, \text{kg/mol}Molecular mass of O₃=3×0.0160kg/molMolecular mass of O₃=0.0480 kg/mol\text{Molecular mass of O₃} = 0.0480 \, \text{kg/mol}Molecular mass of O₃=0.0480kg/mol
Therefore, the molecular mass of ozone is 0.0480 kg/mol.
Explanation:
Ozone (O₃) is a molecule composed of three oxygen atoms. The atomic mass of an element is the mass of a single atom of that element, measured in kilograms per mole (kg/mol). For oxygen, the atomic mass is 0.0160 kg/mol, which means that one mole of oxygen atoms weighs 0.0160 kilograms. By multiplying this atomic mass by 3 (since ozone consists of three oxygen atoms), we can determine the molecular mass of ozone, which is the sum of the masses of all the atoms in the molecule.
This molecular mass is crucial for calculations involving moles of ozone and its interactions in various chemical reactions.
