Question

whosoever will answer my question first I will mark him/her as brainlist ​

Answer 1

Answer:

v of solid=23(current level after its immersion)-15(original level of water=8ml

D=M/V

=30/8=3.75gm/cm^3

mark as brainliest

Answer 2

Answer:

Density of the solid is 3.75 gram per milli litre.

Explanation:

= > Volume of that solid = Volume of the liquid in cylinder( after the solid is immersed ) - volume of the liquid ( solid is not immersed )

= > Volume of solid = 23 mL - 15 mL

= > volume of solid = 8 mL

We know, density = mass / volume.

Here, mass of the solid is 30 gm.

Thus,

= > Density of the solid = 30 gm / 8 mL = 3.75 gram per milli litre.

Hence, density of the solid is 3.75 gram per milli litre.
