Which of the following concentration terms does not correctly represent concentration of aqueous solution of ${\mathrm{NH}}_3$ having molarity 2 M and density 2.034 gm/ml?

Molality = 2 m

$\mathrm{density} =2.034\mathrm{gm}/\mathrm{mp}$

$\text{ Mololity }=\frac{\text{ No. or moles }}{\text{ volume in litres }}$

$\therefore \mathrm{Molarity} =10\times \mathrm{d}\times \mathrm{\omega }$

Here, concentration terms which does not correctly represent concentration is $\mathrm{\%}\mathrm{w}/\mathrm{v}=1.7\mathrm{\%}$
