Question

Order the following substances in increasing form based on their density:
70 degree Gay-Lussac ethanol
API 20 ° oil
15 ° Be hydrochloric acid
15 ° Brix syrup
Acetone-toluene solution (70/30)

Absolute densities (g / ml) of pure substances:
  ethanol 0.790
acetone 0,791
toluene 0.867
sucrose 1,587
Water 0.9982

Answer 1

Density is the property of substance, and it is equals to the mass of the substances divided by its volume.

Ethanol (0.790) Acetone(0.791) < Toluene(0.867)< water(0.998) < Sucrose (1.587).

15 ° Brix syrup < 15 ° Be hydrochloric acid < 20 ° API oil < 70° /30° acetone - Toluene solution < 70° Gay -Lussac ethanol
