20 mL of ethylene glycol has a mass of 20.85 g. The density of ethylene glycol is the mass per unit volume.
`1 mL = 1*10^-6 m^3` , `20 mL = 20*10^-6 m^3`
The density of ethylene glycol is `(20.85*10^-3)/(20*10^-6)` = `1042.5 kg/m^3`
The density of water is `1000 (kg)/m^3`
Density is mass over volume
Density = mass/volume
Density of ethylene glycol = 20.85 g/20.00mL = 1.04 g/mL
now the denity of water is 1g/mL
If we compare this with the density of water, then the density is termed as "specific density"
Specific density is the ratio of the density of the density with the density of the referance
Specific density = density of the substance/density of the reference
Specific density of ethylene glycol=density of ethylene glycol/denityof water
Specific density of ethylene glycol= 1.04 / 1.0 = 1.04
