Which compartment has the higher osmotic pressure? Which compartment has the higher osmotic pressure? 1%% (m/vm/v) starch solution 10%% (m/vm/v) starch solution

Answer : The compartment that has the higher osmotic pressure is, 10 % (m/v) starch solution.

Explanation :

Formula used for osmotic pressure :

where,

= osmotic pressure

V = volume of solution

R = solution constant  = 0.0821 L.atm/mole.K

T= temperature of solution =

M = molar mass of solute

w = mass of solute

Now we have to determine the osmotic pressure for the following solution.

For 1 % (m/v) starch solution :

1 % (m/v) starch solution means that 1 grams of starch present in 100 mL or 0.1 L of solution.

Molar mass of starch = 692.7 g/mol

For 10 % (m/v) starch solution :

10 % (m/v) starch solution means that 10 grams of starch present in 100 mL or 0.1 L of solution.

Molar mass of starch = 692.7 g/mol

From this we conclude that, 10 % (m/v) starch solution has the higher osmotic pressure as compared to 1 % (m/v) starch solution.

Hence, the compartment that has the higher osmotic pressure is, 10 % (m/v) starch solution.
