Which one of the following statements is FALSE?

From the given graph at constant temperature, which gas has the least solubility?

To observe an elevation of boiling point of $0.05°\mathrm{C}$, the amount of solute $\text{(Molecular Weight=100)}$ to be added to $100 \mathrm{g}$ of water (${\text{K}}_{\text{b}}\text{=0.5}$) is _____.
 

Van't Hoff factor of centimolal solution of ${\text{K}}_{\text{3}}{\text{[Fe(CN)}}_{\text{6}}\text{]}$ is $3.333$. Calculate the percent dissociation of ${\text{K}}_{\text{3}}{\text{[Fe(CN)}}_{\text{6}}\text{]}$.

The freezing point of benzene decreases by $0.45°\mathrm{C}$ when $0.2 \mathrm{g}$ of acetic acid is added to $20 \mathrm{g}$ of benzene. If acetic acid associates form a dimer in benzene, percentage association of acetic acid in benzene will be _____. (${\text{K}}_{\text{f}}\text{ for benzene=5.12 K kg/mol}$)

$0.06\% (\mathrm{w}/\mathrm{v})$ aqueous solution of urea is isotonic with _____.

An aqueous solution contains $25\%$ acetic acid and $57\%$ ethanol. The mole fraction of acetic acid ethanol and water in order is given by______. 

If $10 \mathrm{g}$ of a solute was dissolved in $250 \mathrm{mL}$ of water and osmotic pressure of the solution was found to be $600 \mathrm{mm} \mathrm{Hg}$ at $300 \mathrm{K}$, then molecular weight of the solute is ___ $\mathrm{g} {\mathrm{mol}}^{-1}$.
