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.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

i think tornado but not 100%
