Fractional distillation
Explanation:
The best way to separate the mixtures out is through the process of fractional distillation.
In fractional distillation, liquid - liquid mixtures are separated based on the differences in boiling point of their components. Let us examine the boiling points of the component of the mixtures:
Ethanol 78⁰C
Glycerol 290⁰C
Ethylene glycol 197.6⁰C
Methanol 64.7⁰C
Water 100⁰C
We see that the liquids in the mixture have different boiling points. In this process, the mixture is heated in a distillation column. When the boiling point of any component is reached, it will rise up in the column and can be channeled to a condenser where it is cooled and collected.
The liquid with the least boiling point is first separated with the one with the highest boiling is recovered last:
Order of recovery;
Methanol 64.7⁰C
Ethanol 78⁰C
Water 100⁰C
Ethylene glycol 197.6⁰C
Glycerol 290⁰C

Answer:
Mass= volume x density
Explanation:
Multiply the density by the volume.
Empirical formula of the compound contains 5 carbon atoms.
Explanation:
We have the molecular formula of the compound C₁₀H₂₂O₂.
To find the empirical formula we divide each number of atoms by the lowest number which is 2:
for carbon (C) 10 / 2 = 5
for hydrogen (H) 22 / 2 = 11
for oxygen (O) 2 / 2 = 1
The empirical formula is C₅H₁₁O and contains 5 carbon atoms.
