2) S.I.unit of density is kg/m³

mass of the object in air = 80 grams

mass of the object in water = 64 grams

density of water = 1g/cm³

= density of the substance / density of water

= density of the substance / density in water

= 80 / 80 - 64

= 80 / 16

= 5

therefore relative density = 5

i hope it helps.......................^_^

b) si unit of density is kg/m³

(c) weight of the solid in air,w1=80g

weight of the solid in water,w2=64g

relative density=w1/w1-w2

=80/80-64

=80/16

=5

relative density of solid =5

hope it helps...
