Chemistry - Concentration Terms Question with Solution | TestHub

15%$\mathrm{w}/\mathrm{w}$solution weight of solute = 15 g
Weight of solvent = 85 g
$\mathrm{m}=\frac{{\mathrm{w}}_{\mathrm{A}}\times 1000}{{\mathrm{M}}_{\mathrm{A}}\times {\mathrm{w}}_{\mathrm{B}}}$
$=\frac{15\times 1000}{98\times 85}=1.8$
$\left[\mathrm{A}\to \mathrm{S}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{t}\mathrm{e},\mathrm{B}\to \mathrm{S}\mathrm{o}\mathrm{l}\mathrm{v}\mathrm{e}\mathrm{n}\mathrm{t}\right]$
