Question

The molarity of solution obtained by dissolving 0.01moles of NaCl 500ml of solution is

Answer 1

$\huge{\underline{\underline{\red{\mathfrak{Answer :}}}}}$

$\tt Given \begin{cases} \sf{Number \: of \: Moles \: (n) \: = \: 0.01} \\ \sf{Volume \: = \: 500 \: ml} \end{cases}$

As we have formula for Molarity :

$\Large{\underline{\boxed{\sf{m \: = \: \dfrac{Moles}{Volume \: (In \:L)}}}}}$

As we have to convert 500 mL in L so, divide it by 1000

⇒Volume = 0.05

Now put value in formula :

⇒Molarity = 0.01/0.05

⇒Molarity = 0.02 m

∴ Molarity is 0.02 m
