A compound exists in the gaseous phase both as monomer `(A)` and dimer `(A_(2))` The mol wt of `A` is 48 In an experiment `96g` of compound was confined in a container of volume `33.6` litre and heated to `273^(@)C` Calulate the pressure developed if the compound exists as dimer to the extent of `50%` by weight under samae these conditions .

A compound exist in gaseous state both as monomer and dimer. The molecular mass of monomer is 48. In an experiment 96 g of the compound was taken in a vessel of volume 33.6 L at 273 K. What is the pressure developed if the compound exist as a dimer to an extend of 50% by mass?

A mixture containing 1.6 g of O_(2) , 1.4 g of N_(2) and 0.4 g of He occupies a volume of 10 litres at 27^(@)C . Calculate the total pressure of the mixutre and partial pressure of each compound.

The small size and high charge of Al^(3+) ion gives it a high charge density which is responsible for its tendency to show (a) covalency in its compounds in the gaseous state (b) high hydration energy which stabilizes its compounds in solution, and (c) high lattice energy of its compounds in the solid state. Thus aluminium can forms both covalent and ionic bond. Like halides of boron, halides of aluminium do not show back bonding because of increase in size of aluminium. Actually aluminium atoms complete their octets by forming dimers. Thus chloride and bromide of aluminium exist as dimers, both in the vapour state and in polar-solvents like benzene while the corresponding boron halides exists as monomer. In boron trihalides the extent of back bonding decreases with increases with increase in size of halogens and thus lewis acid character increases. All BX_(3) are hydrolysed by water but BF_(3) shows a different behaviour. Which of the following statements about anhydrous aluminium chloride is correct ?
