Question

What is the molarity of a solution made from dissolving 3.00 moles of NaCl into 250 ML of solution

Answer 1

Answer:

$\large \boxed{\text{12.0 mol/L}}$

Explanation:

The formula for molar concentration c is

$c = \dfrac{\text{moles}}{\text{litres}}\\\\c = \dfrac{\text{3.00 mol}}{\text{0.250 L}} = \textbf{12.0 mol/L }\\\\\text{The molar concentration of the solution is \large \boxed{\textbf{12.0 mol/L}} }$
