What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

The answer is: C2H6O.

Molecular formula is chemical formula that shows the total number and kinds of atoms in a molecule, but not their structural arrangement (in this example C6H18O).

Molecular formula shows that compound has six carbon, eighteen hydrogen and three oxygen atoms.

Empirical formula gives the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.

Proportion of atoms: C : H : O = 2 : 6 : 1.

In this example, molecular formula is divided by three.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
