Answer:
1.54×10^20 atoms
Explanation:
It's done by using the relation
N=n×L where,
N = number of entities present
n= amount of substance (mole)
L= Avogadro's constant which is 6.02×10^23
now from the question, given
n=0.000256
And L=6.02×10^23
N= 0.000256×6.02×10^23
N= 1.54×10^20 atoms
I think it is a and c but i’m not sure
C10H22 is a compound which is the most soluble in CC14 because both are non-polar in nature.
<h3>Why polar solute soluble in polar solvent?</h3>
We know that like dissolve like which means that polar solutes only dissolve in polar solvent while on the other hand, non-polar solutes only dissolve in non-polar solvent.
So we can conclude that C10H22 is a compound which is the most soluble in CC14 because both are non-polar in nature.
