Molar solution means $1 \text{ mole}$ of solute present in

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 $ppm$ level of $F^{-}$ in a $500 \ g$ sample of a toothpaste containing $0.2 \ g$ $F^{-}$ is:

Air is an example of a solution of

If $120 \, g$ of urea (molar mass = $60 \, g/mol$) is dissolved in $1000 \, g$ of water and the density of the resulting solution is $1.15 \, g/mL$,what is the molarity of the solution in $M$?
