1. Molar Mass:
* The molar mass of molybdenum (Mo) is 95.94 g/mol. This means 1 mole of molybdenum weighs 95.94 grams.
2. Avogadro's Number:
* Avogadro's number is 6.022 x 10^23. This represents the number of atoms or molecules in one mole of any substance.
3. Calculation:
* Step 1: Find the number of moles in 1 gram of molybdenum:
(1 g Mo) / (95.94 g/mol Mo) = 0.0104 mol Mo
* Step 2: Multiply the number of moles by Avogadro's number:
(0.0104 mol Mo) * (6.022 x 10^23 atoms/mol) = 6.27 x 10^21 atoms
Therefore, there are approximately 6.27 x 10^21 atoms of molybdenum in 1 gram.
