A density bottle has a mass of 35g when empty, 85g when filled with water and 75g when filled with kerosene. Calculate the density of kerosene in g/cm3.

Answer 1

assume the volume is V

density water=85/V
V=85/densitywater
density kero=75/V

density kero=75*densitywater/85

but density water=1gm/cc
so do the figuring.

Answer 2

YES

Answer 3

mass of bottle=35
mass of water=85-35=50g
mass of kerosene=75-35=40g
therefore,density of kerosene=
mass of kerosene/mass of water=
40g/50g= 4g/5g=1.15

ANS=1.15 g/cm3
