i1*m1 = m2

Thus i1 = 1 - a/2 (a is degree of dimeriation)

1-a/2 = 94/120

a = 0.433

c

this is because osmotic pressure provides a large value for even very small concentrations, hence %error is much lower

d

solute particles dont pass, only solvent does

so there will no new compoundforming

a

Nobled gasses are very insoluble in water due to them only interacting via weak london forces

it decreases as noble gasses only interact via london van der waal forces which get stronger with more mass

thus, as we go down, noble gasses satrt to interact with solvents mroe adn thus increase their solubility

d

1=2 as the excess 2g in 1 just doesnt dissolve as saturation is reached at 18g.

thus the extra 2 g does abolsutel nothing and thus 1=2

a

AS on mixing, the volume also doubles

c

d

w/w is weight of solute/ weight of total solution

a

molality = 72/180 / 1 = 0.4

thus delta Tb = 0.208K

To get boiling point at 3atm, we use integrated clasius capeyron

We know ln p2/p1 = dH/R (1/t2 - 1/t1)

thus p2 = 3, p1 = 1

t1 = 373

t2 to be found

plug the values and you’ll get new bp of water at 3 atm (roughly 407K)

add 0.208 to it to get bp of soln

c

glycerin is a non volatile solute

On adding, a complex is formed which reduces number of particles

a

osmomolarity is just molarity * vant hoff

colloidal solns ALWAYS have lower colligative properties than true solns

only c is false
