Explanation:
it could honestly be wrong but I'm not sure
The element with 8 electrons in its 3d sublevel is Ni,
Nickel. The answer is letter D. The
rest of the choices do not answer the question above.
M(C2H2O)= 12.0*2 +1.0*2 +16.0 = 42 g/mol is a molar mass for empirical formula.
120.6g/mol/42g/mol ≈ 3
So, empirical formula should be increased 3 times,
and molecular formula is C6H6O3.
Answer is D.
