Question

if 5.85g of nacl is dissolved in water and the solution is made up to 0.5 liter the molarity of the solution will be

Answer 1

so the answer is 0.2 mol/litre

Answer 2

Answer : The molarity of the solution will be 0.2005 M.

Solution:

Given weight of NaCl = 5.85 g

Molecular mass of NaCl= 58.44 g/mol

Volume of given solution = 0.5 L

$\text{molarity}=M=\frac{\text{given weight in grams}}{\text{molecular weight}}\times \frac{1}{\text{Volume in litre}}$

$M=\frac{5.86 g}{58.44 g/mol}\times \frac{1}{0.5 L}$

$M=0.2005 \text{Molar}$

The molarity of the solution will be 0.2005 M.
