Question

What is the formula of relative density of a liquid

Answer 1

Answer:

hy dude ur answer is

Explanation:

Relative Density is the ratio of a density of a substance to the density of water at 4°C. So mathematically, RD = Density of a substance ÷ Density of water at 4 ° C. RD= Mass of a substance ÷ Mass of same volume of water at 4°C.

plz mark me as brainliest answer

Answer 2

Relative Density is defined as the ratio of density of a substance to the density of water at 4 ° Celsius.

It is denoted as RD ;

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

The characteristics of RD are :

• It is a ratio of similar quantities.

• it is dimensionless and does not have any unit.

• RD directly gives an index upon which we can say if a substance will float or sink in water.

• RD can be increased by increasing the solute concentration of the substance.
