Question

Calculate the molarity of solution which contains 5.85 gram NaCl present in 100 ml water

Answer 1

the molarity of the given solution is 1M

Answer 2

Bonjour!

Given---›

Mass of solute = 5.85 gram

Volume of solution = 100 mL

To find---›
Molarity of solution

$Molarity = \frac{mass \: of \: solute}{molecular \: mass \: of \: solute} \times \frac{1}{volume \: of \: solution \: in \: liters}$

Molecular mass of NaCl = 58.5 g

Therefore,
$M = \frac{5.85}{58.5} \times \frac{1000}{100} \\ \\ = > M = \frac{1}{10} \times 10 \\ \\ = > M = 1$

So, the molarity of solution is 1 M.

Hope this helps...:)
