When 1.697 grams of a hydrocarbon, C Hy
were burned in a
combustion analysis
apparatus, 5.735 grams
of CG2 and 1.174 grams
of H2O were produced.
In a separate experiment,
the molar mass of the
compound was found to
be 26.04 g/mol.
Determine the empirical
formula and the
molecular formula of the
hydrocarbon.

it would be a gas formation

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
