Question

Relative density of a substance is 3.2 what is its density in S.I units​

Answer 1

Given:

Relative density of a substance is 3.2.

To find:

Density of that substance in SI unit.

Calculation:

Relative density of any substance is defined as the ratio of density of the substance to the density of water at 4°C.

$\boxed{ \sf{RD = \dfrac{ density \: of \: substance}{density \: of \: water \: at \: {4}^{ \circ} C} }}$

Putting available values in SI unit:

$= > \sf{3.2= \dfrac{ density \: of \: substance}{1000} }$

$= > \sf{density \: of \: substance = 3.2 \times 1000}$

$= > \sf{density \: of \: substance = 3200 \: kg \: {m}^{ - 3} }$

So, final answer is:

$\boxed{ \rm{density \: of \: substance = 3200 \: kg \: {m}^{ - 3} }}$
