1. Molar Mass of Hydrogen
* The molar mass of hydrogen (H) is approximately 1 gram per mole (g/mol). This means that one mole of hydrogen atoms weighs 1 gram.
2. Avogadro's Number
* Avogadro's number is a fundamental constant that represents the number of atoms or molecules in one mole of a substance. It's approximately 6.022 x 10²³ entities per mole.
3. Calculation
* Since one mole of hydrogen weighs 1 gram, and one mole contains Avogadro's number of atoms:
* 1 gram of hydrogen contains 6.022 x 10²³ hydrogen atoms.
Therefore, there are approximately 6.022 x 10²³ hydrogen atoms in one gram of hydrogen.
