1. Find the molar mass of sodium:
* The molar mass of sodium (Na) is approximately 22.99 g/mol.
2. Calculate the number of moles:
* Divide the given mass by the molar mass:
* Moles of Na = (41.23 g) / (22.99 g/mol) = 1.793 moles
3. Use Avogadro's number:
* Avogadro's number states that there are 6.022 x 10^23 atoms in one mole of any substance.
* Multiply the number of moles by Avogadro's number:
* Atoms of Na = (1.793 moles) * (6.022 x 10^23 atoms/mol) = 1.08 x 10^24 atoms
Therefore, there are approximately 1.08 x 10^24 atoms present in 41.23 grams of sodium.
