Understanding the Basics
* Hydrogen Atom: A single hydrogen atom has a mass of approximately 1 atomic mass unit (amu).
* Hydrogen Molecule (H₂): A hydrogen molecule consists of two hydrogen atoms bonded together.
Calculation
1. Mass of one hydrogen atom: 1 amu
2. Mass of two hydrogen atoms (H₂): 1 amu/atom * 2 atoms = 2 amu
Converting to Grams
* 1 amu = 1.66054 × 10⁻²⁴ grams
Therefore, the mass of one hydrogen molecule (H₂) is:
* 2 amu * (1.66054 × 10⁻²⁴ grams/amu) = 3.32108 × 10⁻²⁴ grams
In summary:
* The mass of one hydrogen molecule (H₂) is approximately 3.32108 × 10⁻²⁴ grams.
