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.

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.

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
