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
It Measures an objects speed and location
Explanation:
Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds
