A Solution Containing 6 G Urea Per Litre Is Isotonic Chemistry Question

A solution containing 6 g urea per litre is isotonic with a solution containing

Options

(a) 5.85 g NaCl per litre
(b) 34.2 g sucrose per litre
(c) 36.0 g glucose per litre
(d) 6.0 g sucrose per litre

Correct Answer:

34.2 g sucrose per litre

Explanation:

For isotonic solution, C₁ = C₂ or , n₁ / M₁V₁ = n₂ / M₂V₂.
Given, n₁ / M₁V₁ = 6/60 = 1/10.
For 34.2 g sucrose per litre C₂ = 34.2/342 = 1/10 . i.e. C₁ = C₂ .

  1. Let wt.of sugar =w g per litre
    Both will have same osmotic pressure.
    Therefore,
    w×R×T=6÷50× RT÷ 1
    w= 34.2 g per litre
