On adding salt.....The boiling temperature increases.....

So ∆t= KB * molality
=O.52*(58/58)/4
= O.52*1/4
= 0.13
So increase is 100+.13=100.13°c

The Blue Giant of the Orient is the largest faceted sapphire in the world, with a mass of

vfiekz [6]

The volume of this sapphire in cubic centimeters is 24.4 cm^3

We have the following information;

Mass of the Blue Giant = 486.52 carats

Density of the blue giant = 3.98 g/cm3

Volume of the blue giant = ?

Since the density is given in g/cm3, we must convert the mass to grams.

We have the conversion factor; 5 carats = 1 g

So;

If 5 carats make 1g

486.52 carats make 486.52 carats × 1g/ 5 carats

= 97.30 g

Since;

Density = mass/volume

Volume = Mass/Density

Volume = 97.30 g/3.98 g/cm3

Volume = 24.4 cm^3

Gnoma [55]

The given question is incomplete. The complete question is as follows.

A solution of chloroform ( $CHCl_{3}$ ) and acetone ( $(CH_{3})_{2}CO$ ) exhibits a negative deviation from Raoult's law. This result implies that:

chloroform-chloroform interactions are stronger than chloroform-acetone interactions.

chloroform-chloroform interactions are weaker than chloroform-acetone interactions.

acetone-acetone interactions are stronger than chloroform-acetone interactions.

acetone-acetone interactions are weaker than chloroform-acetone interactions

chloroform-chloroform interactions are weaker than chloroform-acetone interactions AND acetone-acetone interactions are weaker than chloroform-acetone interactions.

Explanation:

It is known that when the forces between the particles of the mixture are stronger than the forces between the particles in the pure liquids then negative deviations from Raoult's law are observed.

Hence, when a solution of chloroform ( $CHCl_{3}$ ) and Acetone ( $(CH_{3})_{2}CO$ ) will exhibit a negative deviation from Roult's law.

Then, chloroform-chloroform interactions should be weaker than chloroform-acetone interactions and acetone-acetone interactions must be weaker than Chloroform-Acetone interactions.

thus, we can conclude that for the given situation chloroform-chloroform interactions are weaker than chloroform-acetone interactions AND acetone-acetone interactions are weaker than chloroform-acetone interactions.
