Question

Q4 Relative density of brass is 8.4 .It means that a piece of brass of any volume has mass 8.4 times that of an equal volume of water.

1 point

True

False​

Answer 1

Yes its true

Lets find density of brass

• Relative Density=8.4

We know

$\boxed{\sf Relative\:Density=\dfrac{Density\;of\;substance}{Density\:of\:water\:at\:4°C}}$

$\\ \sf\longmapsto Density\:of\:Substance=Relative\:Density\times Density\:of\:water\:at\:4°C{}$

$\\ \sf\longmapsto Density\:of\:brass=8.4\times 1000$

$\\ \sf\longmapsto Density\:of\:brass=8400kg/m^3$
