Question

a cubical block weighs 500g in water 620g in air and 520g in kerosene. find the density of kerosene​

Answer 1

Answer:

Weight of block in air = 600gm

Weight of block in water = 500gm

Loss of weight in water = 600 - 500 = 100 gm

Weight of block in kerosene = 520 gm

Loss of weight in kerosene = 600 - 520 = 80 gms

Relative density of kerosene = loss of weight in kerosene ÷ loss of weight in water

= 80 / 100 = 0.8

Relative density of kerosene = density of kerosene/ density of water

Density of kerosene = Relative density of kerosene × density of water = 0.8 ×1 = 0.8 gm / c.c.
