Question

The density of mercury is 13600 kg/m cube.find the relative density of it without calculating by dividing

Answer 1

Answer:

13.6

Explanation:

consider 1 m3 of mercury. weight of 1 m3 mercury will be w = density x volume x acceleration due to gravity(g)

w= 13600x1x10 = 136000

for 1 m3 water

w= 1000x1x10 = 10000

for same volume :

weight of mercury = 13.6 x weight of water

as mercury is 13.6 times heavier than water

it's relative density is 13.6
