Answer:
1.3
Explanation:
Relative density can be obtained from;
Upthrust in liquid/upthrust in water
Upthrust in liquid = Weight in air - Weight in liquid
upthrust in water = Weight in air - Weight in water
Hence;
Relative density = Weight in air - Weight in liquid/Weight in air - Weight in water
Relative density = 3.4 N - 1.5 N/ 3.4 N - 1.9 N
Relative density = 1.9 N/ 1.5 N
Relative density = 1.3
Look forward and never hold your breath
