Certainly! Here's an example of atomic mass and molecular mass:
Atomic Mass: Let's consider the element carbon (C). Carbon has an atomic number of 6, meaning it has 6 protons. The most abundant isotope of carbon is carbon-12 (C-12), which has 6 neutrons. The atomic mass of carbon is therefore approximately 12.01 atomic mass units (amu). This atomic mass represents the average mass of carbon atoms, considering the different isotopes and their relative abundance.
Molecular Mass: Let's consider a simple molecule, water (H2O). In water, we have two hydrogen atoms (H) and one oxygen atom (O). The atomic mass of hydrogen is approximately 1.01 amu, and the atomic mass of oxygen is approximately 16.00 amu. To calculate the molecular mass of water, we add up the atomic masses of its constituent atoms: Molecular mass of water (H2O) = (2 × atomic mass of hydrogen) + atomic mass of oxygen = (2 × 1.01 amu) + 16.00 amu = 18.02 amu Therefore, the molecular mass of water is approximately 18.02 amu. The molecular mass represents the sum of the atomic masses of all the atoms present in a molecule.
