Unknown
Number of moles = ?
Solution:
The mole is a unit of measurement in chemistry used to delineate the number of particles an atom contains.
A mole of a substance contains the avogadro's number of particles.
Number of moles =
Molar mass of CaO = 40 + 16 = 56g/mol
Number of moles = = 1.59moles

Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As,
Therefore, putting the given values into the above formula as follows.
=
= 0.132
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
1.000.000 is the correct answer
