Chemistry - Concentration Terms Question with Solution | TestHub

1.0 m solution means 1 mole solute is present in 1000 g water.

${\mathrm{n}}_{{\mathrm{H}}_2\mathrm{O}}=55.5\mathrm{ }\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{ }{\mathrm{H}}_2\mathrm{O}$

${\mathrm{X}}_{\mathrm{S}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{t}\mathrm{e}}=\frac{{\mathrm{n}}_{\mathrm{S}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{t}\mathrm{e}}}{{\mathrm{n}}_{\mathrm{S}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{t}\mathrm{e}}+{\mathrm{n}}_{{\mathrm{H}}_2\mathrm{O}}}=\frac{1}{1+55.5}=0.0177$
