The molecular weight of urea is $60$. $A$ solution of urea containing $6 \ g$ of urea in one litre is ....... $molar$.

$A$ $10\% (w/v)$ aqueous solution of glucose is prepared. What is the volume in $litre$ of this solution that contains $2 \, \text{moles}$ of the solute?

If the mole fraction of water in a solution of $H_2SO_4$ is $0.85$,then the molality of the solution is:

Calculate the mass percentage of $3 \ g$ of solute $A$ dissolved in $18 \ g$ of water. (in $\%$)

The molarity of a $1 \ molal$ glucose solution having a density of $1.2 \ g/mL$ is: (in $M$)

Calculate the molality of $1 \ L$ solution of $93 \ \%$ $H_2SO_4$ (weight/volume). The density of the solution is $1.84 \ g/mL$.
