Question

1. While determining the density of a solid a student noted down the
following readings.

(i). Mass of the sphere = 81g


(ii) Reading of water level in the cylinder without sphere in it 71 ml


(iii) Reading of water level in the cylinder with sphere in it 80 ml
On the basis of these observations, what should be the density of solid?​

Answer 1

Answer:

mass= 81

volume = final reading - initial reading = 80-71 = 9

since,

density = mass/ volume

therefore, 81/9= 9

9 is the answer
