Explanation:

Step 1: Define

116 g NaCl

Step 2: Identify Conversions

Molar Mass of Na - 22.99 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of NaCl - 22.99 + 35.45 = 58.44 g/mol

Step 3: Convert

$116 \ g \ NaCl(\frac{1 \ mol \ NaCl}{58.44 \ g \ NaCl} )$ = 1.98494 mol NaCl

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

1.98494 mol NaCl ≈ 1.98 mol NaCl
