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

• physics -

density= mass/volume

mass water=50g
mass kerosene=40g

densitykerosene=massk/volume

but volume= masswater/densitywater

densitykerosene=massk*densitywater/massk

check that.
