Properties, whose values depend only on the concentration of solute particles in solution and not on the identity of the solute are called colligative properties.there may be change in number of moles of solute due to ionisation or association hence these properties are also affected.Number of moles of the product is related to degree of ionisation or association by van Hoff factor 'i' given by i=[1+(n-1)alpha] for dissociation where n is the number of products (ions or molecules ) obtained per mole of the reactant. & i=[1+(1/n-1)alpha] for association where n is number of reactant particles associated to give 1 mole product.A dilute solution contains 't' moles of solute X in 1 kg of solvent with molal elevation constant K_b .The solute dimerises in the solution according to the following equation.The degree of association is alpha . 2X hArr X_2 The colligaive properties observed will be

In the diagram (given below), the broken lines represent the paths followed by particles W, X, Y and Z respectively through the contant field E. The number below the field represent meters. If the particles are positively charged, which particles increased their electric potential energy constant, none of the particle increased their electric potential energy

Calculate the number of moles for the following: (i) 52 g of He (finding mole from mass) (ii) 12.044 × 10_(23) number of He atoms (finding mole from number of particles).

Which of the following may be representing graph between number of scattered particles detected (N) and scattering angle (theta) in Rutherford's experiment?

Avogadro's law states that under similar condition of T and P, equal number of particles. Experiments show that at one atmosphere pressure and at a temperature 273 K (i.e. at STP) one mole of any gas occupy a volume approximately 22.4 litre. Therefore number of moles of any sample of gas can be found by comparing its volume at STP with 22.4. 1 mole of any species contains 6.023xx10^(23) particles which is denoted by symbol N_(A) . Number of atoms present in 1 gm-atom of an element or number of molecules present in 1 gm-molecule of any substance is equal to N_(A) . Hence it is number of particles present in one mole of the substance. If N_(AV) is Avogardo's number, then 10 amu will be equal to _________ gram.
