$0.06 \% (w/v)$ aqueous solution of urea is isotonic with:

At $300 \, K$,$36 \, g$ of glucose present in a litre of its solution has an osmotic pressure of $4.98 \, bar$. If the osmotic pressure of the solution is $1.52 \, bar$ at the same temperature,what would be its concentration?

$3 \ mL$ of solution was made by dissolving $20 \ mg$ of protein at $0^{\circ} C$. The osmotic pressure of the resulting solution is $3.8 \ torr$. The molecular weight of the protein is approximately $(g/mol)$

Pickles have a long shelf life and do not get spoiled for months,why?

The ideal method to determine osmotic pressure is ...... .

Which inorganic precipitate acts as a semipermeable membrane,or what is the chemical composition of a semipermeable membrane?
