Answer:
3.45 moles Li contains 2.08
×
10
(to the power of)24 atoms
.
Explanation:
The relationship between atoms and moles is:
1 mole atoms
=
6.022
×
10
(to the power of)23
atoms
In order to determine how many atoms occupy a given number of moles, multiply the given moles by
6.022
×
10
(to the power of)23
atoms/mole
.
In the case of 3.45 moles lithium (Li):
3.45
mol Li
×
6.022
×
10
(to the power of)23 atoms Li/
1
mol Li
=
2.08
×
10
(to the power of)24
atoms Li rounded to three
The relative volumes of chloroform and water that should be used is 9:10
Concentration of solution in chloroform =
( moles of chloroform )
Concentration of solution in water =
( moles of water )
Dissociation constant at
; 
Concentration of solution in chloroform / Concentration of solution in water
Meaning;

Since
mole is present in chloroform and
mole is present in water, Total mole of Caffeine present is 
Now, we substitute our given values into the equation

Therefore, the relative volumes of chloroform and water that should be used is 9:10
