Ethyl ethanoate is used as a solvent for varnishes and in the manufacture of artificial leather. The formula below represents a molecule of ethyl ethanoate. Write the empirical formula for this compound.

The empirical formula for the ethyl ethanoate molecule is C2H4O.

Explanation:

Ethyl ethanoate is an ester which is formed together with water when ethanol reacts reversibly with acids. This can be illustrated below:

CH3COOH +. C2H5OH <----> CH3COOC2H5 +

H2O

Ethyl ethanoate can be used as an important solvent for varnishes and in the manufacture of artificial leather.

Different formulas can be used to illustrate a chemical compound.

--> Empirical formula of a compound is used to illustrate the simplest whole-number ratio of atoms in a compound.

--> Structural formula of the compound gives an illustration of how the atoms of the compound are bonded to each other.

--> Molecular formula shows the number of each type of atom in a molecule.

The formula given, the molecular formula of the compound is C4H8O2:

C4 H8 O2

4 : 8 : 2

Using 2 to divide through to get the simplest ratio gives rise to C2H4O as the empirical formula.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
