Question

how many grams of hair oil can be poured into a bottle of 400 m^3 capacity ? given that density of a hair oil is 0.84g/cm^3
pls tell fast​

Answer 1

Mass of empty density bottle = 30 gm

mass of density bottle with water in it  62 gm

Mass if density bottle with the liquid = 54 gm

Mass of water only = 62-30=32 gm

(a) Now volume of 1 g of water = 1cm  3

∴ Volume of density bottle = 32 cm  

 

(b) Mass of liquid only = 54-30=24 gm

∴ density of the liquid = ∴  Volume of liquid/ Mass of liquid only

​  

 =  32cm  24g

​ =0.75g/cm
