4. A piece of unknown material has an indefinite shape. It has a mass of 126 g. You submerge it to find it displaces 422 ml of water. What is the relative density of the piece?
Answers
Answer:
Density=Mass/Volume
= 126/422
= 0.2985g/cc
Sp gravity = 0.2985g/cc/densityof water
= 0.2985g/cc/1.0g/cc
=0.2985

Expert Answer
Step 1
Density may be defined as mass of a substance per unit volume.
Mathematically,
fullscreen
Step 2
Given information:
Mass of material = 126.0 g
Volume of water displaces = 422 mL
The amount of water displaced is because of the volume of substance.
and,
Volume of water displaces = volume of material
Thus, we can say,
Volume of material = 422 mL
Step 3
Plugging value of mass and volume in density fo...
