Question

answer the following question​

Answer 1

Answer :

We know that " Sum of mole fraction in a solution is equals to unity "

Given , A + B + C = 0.4 mole

We know A + B + C + D = 1

⇒ ( A + B + D ) + C = 1

⇒ 0.4 + C = 1

⇒ C = 1 - 0.4

⇒ C = 0.6 mole

So , the mole fraction of 'C' is 0.6 mole .
