Expert Answer:
Mass of liquid-1 = volume × density = ( 10 × 10-3 m3 ) × ( 1.80 × 103 kg m-3 ) = 18 kg
Mass of liquid-2 = ( 8 × 10-3 m3 ) × ( 0.80 × 103 kg m-3 ) = 6.4 kg
Total mass of mixture = ( 18.0 + 6.4 ) kg = 24.4 kg
Volume of mixture = ( 10 + 8 ) × 0.9 L = 16.2 L
Density of mixture = mass / volume = ( 24.4 kg ) / ( 16.2 × 10-3 m3 ) = 1.506 × 103 kg/m3
Relative density = density / density of water = 1.506 × 103 / 103 = 1.506
