Question

Density of mercury is 13.6×10^3 kg/m^3. Find the relative density of mercury.

Answer 1

Relative density = Density of substance÷ Density of water

Relative density = 13.6 × 10³ ÷ 10³

Relative density = 13.6

Answer 2

Relative Density Of Mercury = 13.6 kg/m^3

Given:

Density of Mercury = 13.6×10^3 kg/m^3

To Find:

Relative Density Of Mercury

Calculating:

The Formula That Is Used To Calculate Relative Density:

$Relative\:Density = \frac{Density\:Of\:Substance}{Density\:Of\:Water}$

We know that the Density of water is 10^3 kg/m^3

Substituting all the values which are known to us in this formula we get:

$= \frac{13.6\:\times\:10^{3} }{10^{3} }$

$= 13.6\:\times\:10^{3} \:\times\:10^{-3}$

(When exponent goes to the numerator the sign changes if the sign was positive it will be negative and if it was negative it would be positive)

$= 13.6\:\times\:10^{3 - 3}$

(Subtracting the exponents by following exponent rule)

$= 13.6\:\times\:10^{0}$

$= 13.6\:\times\:1$

(Any number raised to 0 will give the answer as 1)

$= 13.6kg/m^{3}$

Therefore, the relative density of mercury is 13.6 kg/m^3
