200 mg of protein is dissolved in 20ml of a solution. If the osmotic pressure of the solution is 15mm of hg at 298k, calculate the molecular mass of protein.

Calculate the osmotic pressure of a decimolar solution of glucose at 30_@ C

A solution containing 30 g of protein per litre exerts an osmotic pressure of 9.4 mm Hg at 25^@C . What is the molecular mass of protein ?

2.75 g of Na_2 CO_3 is present in 200 ml of Na_2CO_3 solution. Calculate the molarity of the solution.

The osmotic pressure ofa solution containing 50 g of a solute in one litre of solution at 300K is 20.5 atmosphere. Calculate the molecular mass of the solute.

The osmotic pressure of a solution is 2.4 atm at 27^@ C. if its strength is 18 g//litre , find molecular mass of the solute.

A solution of protein (extracted from crabs) was prepared by dissolving 0.75 g in 125 cm^3 of an aqueous solution. At 4^@C an osmotic pressure rise of 2.6 mm of the solution was observed. Then molecular weight of protein is (Assume density of solution is 1.00 g/cm^3 ):
