18 g of glucose $${ (C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 })$$ is added to 178.2 g of water. The vapour pressure of water for this aqueous solution at $${ 100 }^{ \circ  }C$$ is ?

Gay Lussac's law is not valid for which chemical reaction?

A mixture of 50.ml of $$N{H_3}$$ and 60.0 ml of $${O_2}$$ gas react as
$$4N{H_3}(g) + 5{O_2}(g)\xrightarrow{{}}4NO + 6{H_2}O(g)$$
If all the gases are at the same temperature and the reaction continues until one of the gases is completely consumed, what volume of water vapour is produced?

The equilibrium constant for the following equilibrium is given at $$0^0C$$:

Calculate the mass of a non - volatile solute (molar  mass $$40\,\,g mol^{-1}$$) which should be dissolved in $$114g$$ octane to reduce its vapour pressure to $$80\%$$

At $${40^ \circ }C$$ the vapour pressure ( in torr ) of a mixture of methyl alcohol and ethyl alcohol is represented by $$P = 199x + 135$$
(where $$x$$ is the mole fraction of methyl alcohol) 

Calculate the vapour pressure of aqueous 0.1 m glucose solution at 300 K temperature, the vapour pressure of water is 0.03 bar at 300 K temperature.

$$5.0\ L$$ water placed in a closed room of volume $$2.5\times 10^{4}L$$ having temperature $$300\ K$$. If vapour pressure of water is $$27.0\ mm$$ and density is $$0.990\ g/cm^{3}$$ at this temperature, how much water is left in liquid state?  

At a certain temperature pure liquid A and liquid B have vapour pressures 10 torr and 37 torr respectively. For a certain ideal solution of A and B, the vapour in equilibrium with the liquid has the components A and B in the partial pressure ratio $$P_A : P_B=1 : 7 $$. What is the mole fraction of A in the solution? 

When the pressure on a gas is decreased to $$1/4$$ and the absolute temperature is increased four-fold the volume of the gas is:
