The molar mass of hydrogen (H₂) is calculated as 2.01568 g/mol.
Here's a breakdown of how to calculate it:
-
Understanding Molar Mass: Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol).
-
Hydrogen's Atomic Weight: The atomic weight of a single hydrogen atom (H) is approximately 1.00784 atomic mass units (amu).
-
Diatomic Nature of Hydrogen Gas: Hydrogen exists in nature as a diatomic molecule (H₂), meaning two hydrogen atoms are bonded together.
-
Calculation: To find the molar mass of H₂, multiply the atomic weight of hydrogen by 2:
- 00784 amu/atom * 2 atoms/molecule = 2.01568 amu/molecule
Since 1 amu is approximately equal to 1 g/mol, the molar mass of H₂ is approximately 2.01568 g/mol.
In summary, the calculation is:
Molar Mass (H₂) = 2 Atomic Weight (H) = 2 1.00784 g/mol = 2.01568 g/mol
