What is the expected freezing point of a 0.50 m solution of na2so4 in water kf for water is 1.86°c/m?

The expected freezing point of a 0.50 m solution of sodium sulfate is -0.93°C.

Explanation:

where,

=depression in freezing point =

= freezing point constant

m = molality

we have :

=1.86°C/m ,

m = 0.50 m

Freezing point of pure water = T =  0°C

Freezing point of solution =

The expected freezing point of a 0.50 m solution of sodium sulfate is -0.93°C.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

since electrons are negative the answer is neagtaive
