1 % (w/w) solution of a compound is isotonic with 5 % (w/w) sucrose (sugar) solution. The molecular weight of the compound will be:
1. | 32.4 | 2. | 68.4 |
3. | 129.6 | 4. | 34.2 |
From the colligative properties of a solution, which one is the best method for the determination of molecular weight of proteins & polymers:
1. Osmotic pressure
2. Lowering of vapour pressure
3. Lowering of freezing point
4. Elevation in boiling point
A solution contains a non-volatile solute of molecular mass M2. The molecular mass of solute in terms of osmotic pressure is:
where:
m2 → Mass of solute
V → Volume of solution
\(\pi\) → Osmotic pressure
