The molality (in $mol \ kg^{-1}$) of $1 \ mol$ of solute in $50 \ g$ of solvent is

Calculate $(a)$ molality,$(b)$ molarity,and $(c)$ mole fraction of $KI$ if the density of $20 \%$ (mass/mass) aqueous $KI$ solution is $1.202 \, g \, mL^{-1}$.

The molarity of urea (molar mass $60 \ g \ mol^{-1}$) solution obtained by dissolving $15 \ g$ of urea in $500 \ cm^3$ of water is

When is the parts per million $(ppm)$ unit used?
