Solution
The correct option is A1300kg/m3 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. The volume is calculated. 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 = 18×10−6m3. Now the density of the liquid is given as, 23.4×10−3m318×10−6m3=1300kg/m3.
