<span> ca. 0.4 moles. if this helps plz medal!</span>
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.
Answer:
<u><em>METALS</em></u>
Lose their valence electrons easily/ ionic by electron loss.
<u><em>NOMETAL</em></u>
Gain or share valence electrons easily/ ionic by electron grain.
