Calculate the density of an aqueous solution of $KI$,if its molarity and molality are $1.44 \ M$ and $1.5 \ mol \ kg^{-1}$ respectively. (in $g \ mL^{-1}$)

The molarity of a solution of $Na_2CO_3$ having $10.6 \ g$ in $500 \ mL$ of solution is ......... $M$.

$450 \ mg$ of glucose is dissolved in $100 \ g$ of solvent. What is the molality of the solution (in $m$)?

$200 \ mL$ of a solution contains $5.85 \ g$ dissolved sodium chloride. The concentration of the solution will be .......... $molar$ $(Na = 23; Cl = 35.5)$.

$34.2 \ g$ of sugar is dissolved in $1.8 \times 10^{2} \ g$ of water to form sugar syrup. Calculate the mole fraction of sugar. (Molar mass of sugar $= 342 \ g/mol$,water $= 18 \ g/mol$)
