You can use cross multiplication formula
The density of water = 1g/cm³
If 20g in that bottle will give 1g/cm³
Then 21.76g = 1g/cm³ × 21.76g/20g
= 1.088g/cm³
Or
find the volume of the bottle
density of water = 1g/cm³
volume = density × mass
= 1g/cm³ × 20g
= 20 cm3
Find density of the oil using the its volume in the bottle and its mass
Density = mass/volume
= 21.76g ÷ 20cm³
= 1.088g/cm³
The density of water = 1g/cm³
If 20g in that bottle will give 1g/cm³
Then 21.76g = 1g/cm³ × 21.76g/20g
= 1.088g/cm³
