The mass of the bottle is given as 30 g.
The mass of the liquid is given as 53.4 g - 30 g = 23.4 g.
The mass of water is given as 48 g - 30 g = 18 g = 0.018 kg.
We know, Density = Mass / Volume.
As the mass of water is determined and the density of water is given, the volume of water is given as follows.
Volume = Mass / Density = 0.018 / 1000 = 18×10

Answer:
1799 g/cc
Explanation:
The mass of bottle = 30g
The mass of kerosene = 54 kg - 30 g
54000 g - 30 g = 53970g
( As the volume of bottle is 30 ml and the kerosene is full in that water so the volume of kerosene is also 30ml )
Volume of kerosene = 30 ml = 30 cm3 or 30 cc
Density = mass / volume
Thus,
The Density of kerosene = 53970 g / 30 cc
= 1799 g/cc
And The RD = 1799g/cc / 1 g/cc
= 1799 g/cc
