Explanation: I was going to answer D but fverdell82156 got to it first! So I have to agree with him! It is D!
K is Potassium
Cl is Chlorine
There are 2 elements.
1 mole has 6.02*10^23 molecules in it.
1 nickel (II) chloride molecule, NiCl2, has 1 Ni atom in it.
so 1 mole of nickel (II) chloride molecule has 1 mole of Ni atom in it.
so 100 moles of nickel (II) chloride molecule has 100*6.02*10^23
= 6.02*10^25 Ni atom in it.
