The concentration in $g$ per litre of a solution of cane sugar $(M = 342)$ which is isotonic with a solution containing $6 \ g$ of urea $(M = 60)$ per litre is

An aqueous solution has an osmotic pressure of $4.92 \text{ atm}$ at $300 \text{ K}$. Calculate the molarity of the solution. $(R = 0.082 \text{ L atm mol}^{-1} \text{ K}^{-1})$ (in $\text{ M}$)

Consider separate solutions of $0.500 \, M \, C_2H_5OH \, (aq)$,$0.100 \, M \, Mg_3(PO_4)_2 \, (aq)$,$0.250 \, M \, KBr \, (aq)$ and $0.125 \, M \, Na_3PO_4 \, (aq)$ at $25 ^\circ C$. Which statement is true about these solutions,assuming all salts to be strong electrolytes?

$A$ solution containing $10 \ g/L$ of urea is isotonic with a $5\%$ solution of a non-electrolyte solute. The molecular mass of the non-electrolyte solute is ..... $g/mol$.

Which of the following conditions is correct for reverse osmosis? [$C =$ Concentration of solution in $mol \ L^{-1}$; $T =$ Temperature in Kelvin scale; $P_{ext} =$ External pressure; $\pi = CRT =$ Osmotic pressure]

The osmotic pressure of $0.4\%$ urea solution is $1.66\ atm$ and that of a solution of sugar of $3.42\%$ is $2.46\ atm$. When both the solutions are mixed in equal volumes,then the osmotic pressure of the resultant solution will be ......... $atm$.
