You're missing a unit in your question! To calculate moles, we need to know the mass of NaCl. Here's how to calculate moles if you know the mass:

1. 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

2. Use the following formula to calculate moles:

* Moles = Mass (g) / Molar Mass (g/mol)

Example:

Let's say you have 116.88 grams of NaCl.

* Moles = 116.88 g / 58.44 g/mol = 2 moles

Please provide the mass of NaCl in grams so I can calculate the number of moles for you.
