Question

a liquid X of density 3.36 g/cm3 is poured in au tube ,which contains Hg.A nother liquid Y is poured in left arm with height 8 cm.Upper level OF X and Y are same.W hat is the density of Y?

Answer 1

Density of liquid X = 3.36 gm
The density of the liquid Y can be calculated using the following formula

HxPxG = HyPyG + hHgPHgg

10 × 3.36 = 8 × Py + 2 × 13.6
33.36  = 8 × Py + 27.2
33.36 - 27.2 = 8 Py
6.16 = 8 Py
6.16 ÷ 8 = Py
0.77 = Py

Therefore the density of liquid will be 0.77 gm/cm³.

Answer 2

Density of liquid X-3.36g/ml

Density of liquid Y-dy

Density of mercury - 13.6

height of liquid X is 10 cm

height of liquid y is 8cm

Hy. Dy. g= hx. dx. g +HmDmg

Dy=60.8/8

=0.77=0.8
