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.

i dont know

explanation:

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
