What is the molarity of a salt solution (NaCl) that has 4.0 mol per 8.0 L?

$0.5 \setminus \text{M}$

Explanation:

Molarity is expressed through the equation,

$\text{molarity"="moles of solute"/"liters of solution}$

So here, the molarity will be,

"molarity"=(4 \ "mol")/(8 \ "L")

$= 0.5 \setminus \text{mol/L}$

We can also expressed it as $0.5 \setminus \text{M}$, as $1 \setminus \text{mol/L"=1 \ "M}$.
