1. Find the molar mass of sodium:
* The molar mass of sodium (Na) is 22.99 g/mol. This means that one mole of sodium atoms weighs 22.99 grams.
2. Calculate the number of moles of sodium:
* Divide the given mass of sodium by its molar mass:
* Moles of Na = (46.00 g) / (22.99 g/mol) = 2.00 mol
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number tells us that there are 6.022 x 10^23 atoms in one mole of any substance.
* Multiply the number of moles of sodium by Avogadro's number:
* Number of Na atoms = (2.00 mol) * (6.022 x 10^23 atoms/mol) = 1.20 x 10^24 atoms
Therefore, there are approximately 1.20 x 10^24 atoms of sodium in 46.00 g of sodium.
