The density of liquid $HCl$ is $1.17 \ g/cm^3$. What is its molarity?

If the mole fraction of $H_2SO_4$ in an aqueous solution of $H_2SO_4$ is $0.1$,then the molality of the solution is ........... $m$.

Mole fraction of solute in its $2$ molal aqueous solution is

$A$ solution of sugar is obtained by mixing $200 \ g$ of its $25 \%$ solution and $500 \ g$ of its $40 \%$ solution (both by mass). The mass percentage of the resulting sugar solution is $..........$. (Nearest integer)

If $5.0 \ g$ of $BaCl_2$ is present in $10^6 \ g$ solution,the concentration is .......... $ppm$.

What will be the molality of $10\%$ w/w aqueous solution of $NaOH$ (in $m$)? (Molecular mass of $NaOH = 40 \ g \ mol^{-1}$)
