Answer:
See the answer below
Explanation:
a. The volume in the first measuring cylinder reads 70 while that of the second reads 95
. Hence;
V1 = 70
V2 = 95
b. <u>An object will always displace its own volume in a liquid</u>. Hence:
Volume V of the rock sample = V2 - V1
= 95 - 70 = 25
c. Mass of A = 102 g
Volume of A = 25
<em>Density = mass/volume</em>
Hence, density of A = 102/25 = 4.08 g/
