Question

Find the molarity of a 500 L solution that contains 10 moles of fluorine.

Answer 1

Given :-

• Number of moles = 10
• Volume of solution = 500L

To Find :-

• Molarity of the solution .

Solution :-

As we know that ,

$\longrightarrow Molarity (M )=\dfrac{Number\ of \ moles \ of \ solute }{Volume\ of \ solution\ (in \ L) }$

Substitute ,

$\longrightarrow M =\dfrac{10}{500L}$

Simplify,

$\longrightarrow M = \dfrac{1}{50}$

Convert into decimal ,

$\longrightarrow \underline{\underline{ M = 0.02 \ mol \ L^{-1}}}$

This is the required answer .
