Question

A stone of mass 79.1gm is placed in a cylinder of water the stone sinks to the bottom due to which level of water rise from 33cm3 to 40cm3 mark . Calculate density of the stone

Answer 1

$mass = 79.1 g\\ \\volume = 40 - 33 = 7 cm^3\\ \\density = \frac{mass}{volume}= \frac{79.1}{7} = 11.3 \: g. {cm}^{ - 3} \\ \\ \boxed{density = 11.3 \: g. {cm}^{ - 3} }$

Answer 2

Answer:-

• 79.1g KS the given Mass
• 40−33=7cm is the given Volume

This formula :-(density= volume-mass)

= 779.1

=11.3g.cm −³

=11.3g.cm -³ is the density
