1. Determine the formula for salt

Salt is sodium chloride (NaCl).

2. Find the molar mass of NaCl

* Sodium (Na) has a molar mass of 22.99 g/mol

* Chlorine (Cl) has a molar mass of 35.45 g/mol

* Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol

3. Calculate the moles of NaCl

* Moles = mass / molar mass

* Moles of NaCl = 3.00 g / 58.44 g/mol = 0.0514 mol

4. Determine the mole ratio of sodium ions (Na+) to NaCl

* For every 1 mole of NaCl, there is 1 mole of Na+ ions.

5. Calculate the moles of Na+ ions

* Moles of Na+ = moles of NaCl * (1 mole Na+ / 1 mole NaCl)

* Moles of Na+ = 0.0514 mol * (1/1) = 0.0514 mol

Therefore, there are 0.0514 moles of sodium ions dissolved in the solution.
