Which of the following solutions will have the highest boiling point? a. 1 molar fecl3 solution b. 1 molar cacl2 solution c. 1 molar kcl solution d. 1 molar nacl solution

Explanation:

Ionic compounds are formed when two opposite charge atoms combine together. Therefore, there is strong force of attraction between the ions.

In order to break this ionic bond, high heat is required. As a result, the boiling point of ionic compounds is high.

Out of the given options, , KCl, and NaCl are all ionic compounds because the bond formation in these compounds is due to the transfer of electrons.

Hence, all these solutions have high boiling point.

Whereas is a covalent compound, that is, it is formed by sharing of electrons. There is weak force of attraction between iron and chlorine atoms thus, has low boiling point.

Therefore, we can conclude that solutions with highest boiling point are as follows.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
