1. Calculate the RDA of sodium:
* If 270 mg of sodium is 1/11 of the RDA, then the RDA is 270 mg * 11 = 2970 mg.
2. Convert milligrams to grams:
* 2970 mg * (1 g / 1000 mg) = 2.97 g
3. Calculate moles of sodium:
* Molar mass of sodium (Na) is 22.99 g/mol
* Moles of sodium = (2.97 g) / (22.99 g/mol) = 0.129 moles
4. Calculate the number of atoms:
* Avogadro's number is 6.022 x 10^23 atoms/mol
* Number of atoms = (0.129 mol) * (6.022 x 10^23 atoms/mol) = 7.77 x 10^22 atoms
Therefore, the recommended daily allowance of sodium contains approximately 0.129 moles and 7.77 x 10^22 atoms.
