1. Moles of Sodium
* Molar mass of sodium (Na): 22.99 g/mol
* Formula: moles = mass / molar mass
* Calculation: moles = 2.30 g / 22.99 g/mol = 0.100 moles of sodium
2. Atoms of Sodium
* Avogadro's number: 6.022 x 10^23 atoms/mol
* Formula: atoms = moles x Avogadro's number
* Calculation: atoms = 0.100 mol x 6.022 x 10^23 atoms/mol = 6.02 x 10^22 atoms of sodium
Therefore:
* There are 0.100 moles of sodium in 2.30 grams.
* There are 6.02 x 10^22 atoms of sodium in 2.30 grams.
