Asolution is prepared by dissolving 31.9 g cesium chloride in 60.0 g water. the volume of the solution is 63.3 ml. calculate the molality of the cscl solution.

The molality of the CsCl solution is 3.2 m.

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

moles of solute =

Now put all the given values in the formula of molarity, we get

= weight of solvent (water) in g  = 60.0 g

Molality =

Thus molality of the CsCl solution is 3.2 m.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
