- Carbon (C): Atomic mass ≈ 12.01 g/mol
- Oxygen (O): Atomic mass ≈ 16.00 g/mol
Now, let’s calculate the mole mass of CaCO3:
Molecular Mass of CaCO3 = (Molar Mass of Ca) + (Molar Mass of C) + (3 × Molar Mass of O)
The Molecular Mass of CaCO3 = (40.08 g/mol) + (12.01 g/mol) + (3 × 16.00 g/mol)

Before delving into the molecular weight of hydrogen, it’s essential to understand the atomic weight of a single hydrogen atom. The atomic weight of an element is essentially a weighted average of its isotopes, and hydrogen has three isotopes: protium (¹H), deuterium (²H or D), and tritium (³H or T). However, the atomic weight commonly associated with hydrogen is approximately 1.008 amu (atomic mass units), which corresponds to the most abundant isotope, protium.
Molecular Weight of Hydrogen (H₂)
The molecular weight of hydrogen is calculated by considering a molecule of hydrogen gas, H₂, which consists of two hydrogen atoms. Since each hydrogen atom has an atomic weight of approximately 1.008 amu, the calculation is straightforward:
Molecular Weight of Hydrogen (H₂) = 2 × Atomic Weight of Hydrogen ≈ 2.016 g/mol
Hence, the molecular weight of hydrogen gas (H₂) is approximately 2.016 grams per mole (g/mol). This value is incredibly low, making hydrogen the lightest element and the lightest molecule known.
