$3.0$ molal $NaOH$ solution has a density of $1.110 \ g/mL$. The molarity of the solution is :-

When $5 \ g$ of acetic acid is dissolved in $1 \ L$ of ethanol,assuming no reaction occurs between them,calculate the molality of the resulting solution. (Density of ethanol = $0.789 \ g/mL$) (in $m$)

$248 \ g$ of ethylene glycol $(C_2H_6O_2)$ is added to $200 \ g$ of water to prepare antifreeze. What is the molality of the resultant solution (in $m$)? $(C=12 \ u, H=1 \ u, O=16 \ u)$

The mole fraction of glucose $(C_{6}H_{12}O_{6})$ in an aqueous binary solution is $0.1$. The mass percentage of water in it,to the nearest integer,is $....$.

The molality of $648 \ g$ of pure water is ........... $m$.

$3.42 \times 10^{-2} \ kg$ of sugar (molar mass $342 \ g \ mol^{-1}$) is dissolved in water to produce $234.2 \ g$ of sugar syrup. What is the molality of the sugar syrup?
