Mass of empty bottle =25g
Mass of the bottle full of water = 50 g
Therefore, mass one bottle of water (excluding the mass of the bottle) = 50-25 =25g
Mass of the bottle full if liquid = 45g
So, mass of one bottle of liquid (excluding the mass of the bottle) = 45-25 =20g
Therefore, the reative density of the liquid = 420/25 =0.8
Therefore, the density of the liquid in kg/m^3 = mass of one cubic meter of liquid = 0.8*(100)^3 gram per m^3 = 800kg/m^3
