∆x is given by ∆x=(Hydrogen energy-Lattice energy). For a salt ∆x is found to be 500 kcal mol<sup>-1</sup>.Then on increasing the temperature, its solubility in water

If the length of the unit cell is 5 A<sup>o</sup>. the smallest distance in A<sup>o</sup> between the two neighbouring metal atoms in a face centred cubic lattice is

The weight in grams of a non-volatile solute (M.wt:60) to be dissolved in 90 g of water to produce a relative lowering of vapour pressure of 0.02 is

9.8 g of H_{2}SO_{4}is present in two litres of a solution.The molarity of the solution is:
