Answer:
Mole fraction of
= 0.58
Mole fraction of
= 0.42
Explanation:
Let the mass of
and
= x g
Molar mass of
= 33.035 g/mol
The formula for the calculation of moles is shown below:
Thus,
Molar mass of
= 46.07 g/mol
Thus,
So, according to definition of mole fraction:

Mole fraction of
= 1 - 0.58 = 0.42
