Answer:
density of liquid = 1.5 gm/cc
volume mixed = 50 cc
=> mass of liquid mixed = 1.5 * 50 = 75 gms
density of water = 1 gm/cc
volume mixed = 30 cc
=> water mixed = 3 0 * 1 = 30 gm
Total volume of mixture = 75 + 30 = 105 gms
Density of mixture = 105 gm / 80 cc = 1.3125 gms/cc
BY FORMULA:
density of a mixture = [ V1 * d1 + V2 * d2 ] / (V1 + V2)
= [ 50 * 1.5 + 30 * 1 ] / (50 + 30)
=105 gm/ 80 cc
= 1.3125 gm/cc
