Question

A Solution A and B. If mole
fraction of À is 0.4 . what is the
mole fraction of B ?​

Answer 1

Answer:

0.6

Explanation:

always remember sum of mole fractions equals to one need to know why..let me answer..

mole fraction of A=no of moles of A/no of moles of solution.....(1)

mole fraction of B=no of moles of B/no of moles of solution......(2)

here no of moles of solutions is no of moles of A+no of moles of B.

now adding (1)and (2)..we get '1'..

hope this was useful.

will you mark me as brainliest for my efforts?

Answer 2

Answer:

The answer will be 0.6.

Explanation:
