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
