The molar mass of sodium chloride (NaCl) is 58.44 g/mol. To calculate the number of moles in 117g of sodium chloride, we can divide the given mass by the molar mass:

Moles of NaCl = Mass / Molar mass

Moles of NaCl = 117g / 58.44 g/mol = 2.00 mol

Therefore, there are 2.00 moles of sodium chloride in 117g of sodium chloride.
