The density of $3 \ M$ solution of $NaCl$ is $1.0 \ g \ mL^{-1}$. Molality of the solution is $...... \times 10^{-2} \ m$. (Nearest integer). Given: Molar mass of $Na$ and $Cl$ is $23$ and $35.5 \ g \ mol^{-1}$ respectively.

Explain $\% \ V/V$ in brief.

$1000 \ g$ aqueous solution of $CaCO_3$ contains $10 \ g$ of carbonate. Concentration of the solution is .......... $ppm$.

The density (in $g \ mL^{-1}$) of a $3.60 \ M$ sulphuric acid solution that is $29 \% \ H_2SO_4$ (Molar mass $= 98 \ g \ mol^{-1}$) by mass will be

The molecular weight of glucose is $180$. $A$ solution of glucose which contains $18 \ g$ per litre is ........... $molal$.
