Exercise 33

An osmole contains:

A. One gram molecular weight of solute dissolved in one liter of solvent

B. One gram molecular weight of solute dissolved in one kilogram of solvent

C. Two gram molecular weights of solute dissolved in one liter of solvent

D. Two gram molecular weights of solute dissolved in one kilogram of solvent

Step 1 of 2

Osmole:

• It is a non SI (International System) unit.

• Osmole is mole in solution which contributes to the osmotic pressure of a solution.

Osmotic pressure:

Pressure applied in a solution to prevent inner movement of water in semi-permeable membrane.

• Solute: solute which is to be dissolved. For example-salt.

• Solvent: solvent dissolve the solute. For example-water

• Osmole contain solute of one gram molecular weight dissolving in one kilo gram of solvent.

Therefore, osmole has “one gram molecular weight solute dissolved in solvent of one kilogram”. Hence, the correct answer is option .
