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

Explain the types of solutions based on the physical states of solute and solvent with suitable examples.

$A$ $1000 \ g$ aqueous solution of $CaCO_3$ contains $10 \ g$ of calcium carbonate. The concentration of the solution in $ppm$ is .........

An antifreeze solution is prepared from $222.6 \ g$ of ethylene glycol $[C_2H_4(OH)_2]$ and $200 \ g$ of water. What is the molality of this solution (in $m$)?

When $120 \ g$ of urea (molar mass $= 60 \ g/mol$) is dissolved in $1000 \ g$ of water,the density of the resulting solution is $1.15 \ g/mL$. The molarity of this solution is ........ $M$.

The correct relationship between molality $(m)$ and molarity $(M)$ of a solution is ($d = $ density in $g/mL$ and $M_{solute} = $ molar mass of solute in $g/mol$)
