Question

if the relative density of a substance is 1.2 state its density in the SI system if density of water at 4 degree celsius is 1000 kilometre per cube

Answer 1

Answer:

1.2×10^3kgm^(-3) is the density of the substance

Answer 2

*density must be given in kilogram per meter cube*

$\rho=1200\ kg.m^{-3}$ is the density of the given substance

Explanation:

Given:

relative density of the substance, $S=1.2$

density of water at 4°C, $\rho_w=1000\ kg.m^{-3}$

Now the density of the given substance:

From the definition of the specific gravity:

$S=\frac{\rho}{\rho_w}$

$\rho=1200\ kg.m^{-3}$

TOPIC: specific gravity
