Question

calculate mole fraction of A ,B and C obtained by mixing 10 gram of A , 20 gram of B and 40 gram of C​

Answer 1

Explanation:

Fraction of total components  = 10 + 20 + 40 = 70

Mole fraction of A = 10/70 = 0.14

Mole fraction of B = 20/70 = 0.28

Mole fraction of C = 40/70 = 0.57

To check....

0.14 + 0.28 + 0.57 = 1 (Sum of mole fractions of all components is equal to one)
