The molality of an aqueous solution of glucose is $1.0 \ m$. The mole fraction of glucose is approximately ........

$A$ solution contains $25\%$ ${H_2}O$,$25\%$ ${C_2}{H_5}OH$ and $50\%$ ${CH_3}COOH$ by mass. The mole fraction of ${H_2}O$ would be

An antifreeze solution is prepared from $222.6 \ g$ of ethylene glycol $(C_2H_6O_2)$ and $200 \ g$ of water. Calculate the molality of the solution. If the density of the solution is $1.072 \ g \ mL^{-1}$,then what shall be the molarity of the solution?

Which of the following modes of expressing concentration is independent of temperature?

Assertion $(A)$: Molality of a solution increases with temperature.
Reason $(R)$: Molality expression does not involve any volume term.

The molarity of a $70 \%$ (mass/mass) aqueous solution of a monobasic acid $(X)$ is $........... \ M$ (Nearest integer). Given: Density of aqueous solution of $(X)$ is $1.25 \ g \ mL^{-1}$,Molar mass of the acid is $70 \ g \ mol^{-1}$.
