Answer:
Mass of empty density bottle (M
1
)=30g
Mass of bottle + water (M
2
)=75g
Mass of liquid + Liquid (xM
3
)=65g
Mass of water =M

=75−30=45g
(a) Volume of density bottle = Mass of water 45g
(b) Density of liquid x=

=0.77 g/cm

(c) Mass of water in the density bottle =75−30=45g
∴ Volume of water in density bottle =45cc
and mass of the equal volume of liquid in density bottle 65−30=35g
R.D. of liquid =
mass of 45 cc of water
mass of cc of liquid
=
