One of your friends defines molality as follows. “It is the number of gram moles of the solute dissolved per litre of solution:Calculate the molality of a solution containing 20 g of NaOH in 250g of H_2O .

One of your friends said that radius ratio of NaCl is 0.52 .Can you predict geometery of voids and cordination number of NaCl?

Define the following terms: i. Mole tion fi. Molality ifi. Molarity iv. Mass percentage.

In each of the following question, an Assertion (A) is following by a corresponding Reason (R ). Use the following keys to choose the appropriate answer. Assertion : Molarity of a solution does not depend upon temperature whereas molality depends. Reason : Molarity and molality both depend only on the number of moles of solute particles.

One mole of a solute Ais dissolved in a given volume of a solvent. The association of the solute takes place as follows: n A Leftrightarrow A_n If alpha is the degree of association of A the van't Hoff factor i is expressed as:

The molal b.pconstant '(fK_h)' for water is '0.513^circ C' kgmol". When 0.1 mole of sugar is dissolved 'in '200 ~g' of water, the solution boils under a pressure of 1 atm. At
