in 3 mol of solvent is 0.5 then select the correct
statement among the following
(1) Solute is remain unionized
(2) 25% solute is ionised
(3) 50% solute is ionised
(4) 75% solute is ionised​

Answer 1

Answer:

sorry bro i dont know answers that answer is in google ithis is the link bro https/:

Answer 2

Answer:

(2)25% solute is ionised

Explanation:

here i=1+alpha(degree of diss.)

also i=observed/calculated coliigative property

equating the two,

1+alpha=0.5/0.4

alpha=0.25

hence solute is 25% ionised
