Answer:

Just use a text book.. So that you get the concept

Hence, [tex]C_{20}H_{20}O_4[/tex] is the molecular formula of a compound's empirical formula is [tex]C_5H_5O[/tex].

What is an empirical formula?

The empirical formula is the chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the actual numbers or arrangement of atoms.

Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number

The molar mass of the empirical formula compound [tex]C_5H_5O[/tex] is 46.06844 g/mol.

The molecular mass of the compound is 162.2g given.

162.2g ÷ 46.06844

3.520848546 =4

[tex]C_{20}H_{20}O_4[/tex] is the molecular formula.
