A spherical balloon of $$21\ cm$$ diameter is to be filled up with $$H_2$$ at $$NTP$$ from a cylinder containing the gas at $$20\ atm$$ at $$27^{\circ}C$$. The cylinder can hold $$2.82$$ litre of water. The number of balloons that can be filled up

The vapour pressure of a given liquid will decrease if:

An aqueous solution containing liquid $$A(M.\ wt.\ =128)\ 64\%$$ by weight has a vapour pressure of $$145\ mm\ Hg$$. If the vapour pressure of water is $$155\ mm\ Hg$$ then vapour of $$A$$ at the same temperature will be

The solubility of a specific non-volatile salt is 4g in 100 g of water at $${25}^{0}$$C. If 2.0g, 4.0g and 6.0g of the salt added of 100g of water at $${25}^{0}$$C, in system X, Y and Z. The vapour pressure would be in the order:

The pressure exerted by a mass of x mg resting on the area of 1.00 $${ cm }^{ 2 }$$ is 1.00 Pa, then x is

Reaction of $${NO}$$ takes place with hydrogen if equal molar mixture of snow and hydrogen is taken at initial total pressure of 350 mm of Mercury, total pressure reduces to half its value after 121 seconds while if initial total pressure would have been 275 mm it reduces to half of the 196 seconds calculate the order of reaction?

The vapour pressure of pure water at $$25^{\circ}C$$ is $$30\ mm$$. The vapour pressure of $$10\%\ (W/W)$$ glucose  solution at $$25^{\circ}C$$ is :

Relative decrease in vapour of an aqueous $${\text{NaCl}}$$ is $$0.167$$. Number of moles of $${\text{NaCl}}$$ present in $$180\ g$$ of $${{\text{H}}_{\text{2}}}{\text{O}}$$ is:

The vapour pressure of pure benzene at a certain temperature is 200 mm Hg. At the same temperature the vapour pressure of a solution containing 2 g of non volatile non electrolyte solid in 78 g of benzene is 195 mm Hg. What is the molecular mass of solid?

Calculate vapour pressure of solution obtained by mixing 0.1 mol of $$K_4[Fe(CN)_6]$$ to 360 gm of water at $${27}^0C$$. [Given: Vapour pressure of pure water at 27C is 25 torr.]
