Answer: The partial pressure of the Kr is 320 mm Hg.
Explanation:
According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as
where, = partial pressure of component A
= mole fraction of A
= total pressure
mole fraction of Krypton =
Thus partial pressure of the Kr is 320 mm Hg
Ca= 2 ve
Be=2 ve
Mg=2 ve because they are in Group 2a.
They are slightly less reactive than Group 1a, but more dense that Group 1a.
