Which molecular formula and empirical formula represent this compound?
1 answer:
According to picture below, answer is d.c4h2n2o4 and c2hno2.
Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this case C₄H₂N₂O₄). Molecular formula shows that compound has four carbon, two hydrogen, two nitrogen and four oxygen atoms.
Empirical formula gives the proportions of the elements present in a compund but not the actual numbers or arrangement of atoms. C : H : N : O = 2 : 1 : 1 :2.
