18 g glucose and 6 g urea are dissolved in 1 L aqueous solution at 27^(@)C . The osmotic pressure of the solution will be a. 8.826 atm , b. 4.926 atm ,c. 2.92 atm , d. 4.42 atm

A simple of thliqid H_(2)O at 18.0 g is inlected into an evacuated 7.6 L flask maintained at 27.0^(@)C . If vapour pressure of H_(0)O at 27.0^(@)C is 24.63 mm Hg, what wight percentage of the water will be vaproueied when the ssystem comes to equilibrium? Assume water vapours behaves as an ideal gas. The volume occupied by the liquid water is negligible compared to the volume of the container:

18 g mixture of hellium and argon occupied 30 L at 1 atm pressure and 27^(@)C . Calculate the percentage of these gases in the mixture.

A solution is prepared by dissolving 0.6 g of urea (molar mass =60 g"mol"^(-1) ) and 1.8 g of glucose (molar mass =180g"mol"^(-1) ) in 100 mL of water at 27^(@)C . The osmotic pressure of the solution is: (R=0.08206L "atm"K^(-1)"mol"^(-1))

2.8 g of N_(2) 0.40 g of H_(2) and 6.4 g of O_(2) are placed in a container of 1.0 L capacity at 27^(@) C. The total pressure in the container is

The pressure exerted by a non-reactive gaseous mixture of 6.4g of methane and 8.8 g of carbon dioxide in a 10L vessel at 27^(@)C is "__________" kPa. ( Round off to the Nearest Integer ). [ Assume gases are ideal, R = 8.314] mol^(-1) K^(-1) Atomic masses : C : 120 u, H : 1.0 u, O : 16.0 u ]
