Calculate the molality of $2.5 \ g$ of ethanoic acid $(CH_{3}COOH)$ in $75 \ g$ of benzene.

$3.0\, g$ of oxalic acid $[(CO_2H)_2 \cdot 2H_2O]$ is dissolved in a solvent to prepare a $250\, mL$ solution. The density of the solution is $1.9\, g/mL$. The molality and normality of the solution,respectively,are closest to

What is the concentration of nitrate ions if equal volumes of $0.1 \, M$ $AgNO_3$ and $0.1 \, M$ $NaCl$ are mixed together (in $, M$)?

The molality of $1 \ M$ solution of $NaCl$ (specific gravity $1.0585 \ g/mL$) is

What is the final molarity of a solution obtained by mixing $480 \, mL$ of $1.5 \, M$ solution and $520 \, mL$ of $1.2 \, M$ solution (in $, M$)?

The molality of a solution,when $18 \ g$ of glucose is added to $18 \ g$ of $H_2O$,is: (in $m$)
