Osmotic pressure of insulin solution at 298 K is found to be 0.0072 atm . Hence, height of water column due to this pressure is [given d(Hg)=13.6g/mL ]

Question

Osmotic pressure of insulin solution at 298 K is found to be 0.0072 atm . Hence, height of water column due to this pressure is [given d(Hg)=13.6g/mL ] (A) 0.76cm (B) 0.70 cm (C) 7.4 cm (D) 76 cm

Tardigrade Admin · Accepted Answer

p=0.0072 atm =0.0072 × 76 cm of Hg =0.0072 × 76 × 13.6 cm of mercury column Also, p=h × 1 cm of water column ∴ h × 1=0.0072 × 76 × 13.6 cm or h=7.4 cm

Q. Osmotic pressure of insulin solution at $298 K$ is found to be $0.0072 a t m$ . Hence, height of water column due to this pressure is [given $d (H g) = 13.6 g / m L$ ]

0.76cm

0.70 cm

7.4 cm

76 cm

$p = 0.0072 a t m$
$= 0.0072 \times 76 c m$ of $H g$
$= 0.0072 \times 76 \times 13.6 c m$ of mercury column
Also, $p = h \times 1 c m$ of water column
$∴ h \times 1 = 0.0072 \times 76 \times 13.6 c m$
or $h = 7.4 c m$
