π=C R T π (sucrose) =π (glucose) C (sucrose) RT = C (glucose) RT No. of moles of glucose = No. of moles sucrose Is 18.0 g of glucose

Q. An aqueous solution of sucrose containing $34.2 g / ℓ$ has an osmotic pressure of $2.38$ atmosphere at $1 7^{\circ} C$ for an aqueous solution of glucose, $C_{6} H_{12} O_{6}$ to be isotonic with this solution, it would have

$34.2 g / ℓ$

$17.1 g / ℓ$

$18.0 g / ℓ$

$36.0 g / ℓ$

$π = CRT$
$π$ (sucrose) $= π$ (glucose)
$C$ (sucrose) $RT = C$ (glucose) $RT$
No. of moles of glucose $=$ No. of moles sucrose
Is $18.0 g$ of glucose

34.2g/ℓ

17.1g/ℓ

18.0g/ℓ

36.0g/ℓ
