What is the empirical formula of C6H18O3?
Aloiza [94]

Answer:

The answer to your question is C₂H₆O

Explanation:

Data

Molecular formula = C₆H₁₈O₃

Empirical formula = ?

Empirical formula is defined as the simplest ratio of the elements that form part of a molecule.

Process

To find the empirical formula find the greatest common factor of the subscripts.

                             6    18   3   2

                             3      9  3   3

                              1     3    1   3

                                     1

The GCF is 3, so factor 3 of the molecular formula

                         3 ( C₂H₆O)  

The result is the empirical formula C₂H₆O

Summarize at least three steps needed to carry out Galileo's famous experiment to determine whether heavier objects
LenaWriter [7]

Answer:

Explanation:

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers have taken to replicating this test in a way that the Italian scientist probably never envisioned — by dropping atoms. One of Galileo's contributions to the founding of modern science was his study of falling objects.  He turned, then, to measuring the acceleration of objects rolling down smooth ramps. The ramp "diluted" the acceleration to a value small enough to allow accurate measurements of the longer time intervals.
