What you the mass number of H2o?
The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.
Can the atomic mass of a molecule be found if the chemical formula is known?
Well first of all a molecule doesn't have an atomic mass it has a molecular mass. It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a periodic table. For example water has a formula of H20. This means it is made of 2 hydrogen atoms and 1 oxygen atom. Hydrogen has an atomic mass of 1 g/mol while oxygen has an atomic mass of 16 g/mol. So the molecular mass of water is 2 x 1g/mol + 1 x 16 g/mol = 18 g/mol
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
