Answer:
<em>The accurate label for the solution is</em><em> </em><u><em>2.00 mol/L NaCl.</em></u>
Explanation:
Molrity = mass ÷ molar mass
Molar mass of NaCL = 58.44 g/mol
Weighed mass = 116.9g
⇒ Molarity of the solution = 
= 2.0M
<em />
<em>Therefore, the accurate label for the solution is </em><u><em>2.00 mol/L NaCl.</em></u>
