What will be the osmotic pressure of a $10\%$ sugar solution at $69\,^oC$ (in $, atm$)? (Molar mass of sugar $= 342 \, g/mol$)

$A$ solution containing $4 \ g$ of a non-volatile organic solute per $100 \ mL$ has an osmotic pressure of $500 \ cm$ of mercury at $27^\circ C$. What is the molar mass of the solute?

$A$ solution is prepared by dissolving $0.6 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) and $1.8 \ g$ of glucose (molar mass $= 180 \ g \ mol^{-1}$) in $100 \ mL$ of water at $27 \ ^oC$. The osmotic pressure of the solution is : ............. $atm$ $(R = 0.08206 \ L \ atm \ K^{-1} \ mol^{-1})$

The average osmotic pressure of human blood is $7.8 \ bar$ at $37\ ^oC$. What is the concentration of an aqueous $NaCl$ solution that could be used in the blood stream (in $mol/L$)?

An aqueous solution of $0.6 \% (w/v)$ urea is isotonic with which of the following?

$1.46 \, g$ of a biopolymer dissolved in a $100 \, mL$ water at $300 \, K$ exerted an osmotic pressure of $2.42 \times 10^{-3} \, bar$.
The molar mass of the biopolymer is $..... \times 10^{4} \, g \, mol^{-1}$. (Round off to the Nearest Integer)
[Use : $R = 0.083 \, L \, bar \, mol^{-1} \, K^{-1}$ ]
