Arrange the following aqueous solutions in order of increasing boiling points 0.050 m mg(no3): 0.100 m ethanol 0.090 m nacl ethanol

The order of increasing boiling points follows:

Explanation:

The expression of elevation in boiling point is given as:

where,

= Elevation in boiling point

i = Van't Hoff factor  

= change in boiling point

= boiling point constant

m = molality

For the given options:

Value of i = 3

So, molal concentration will be =

Value of i = 1  (for non-electrolytes)

So, molal concentration will be =

Value of i = 2

So, molal concentration will be =

As, the molal concentration of NaCl is the highest, so its boiling point will be the highest.

Thus, the order of increasing boiling points follows:

the dependant variable is spilled water

the independent is the heat
