Question

I HAVE TEST PLS HELP WITH STEPS NOW PLS

An empty bottle weighs 80g. When the bottle is filled with water it weighs 120g.
When it is filled with coconut oil it weighs 160g. What is the relative density of
coconut oil with respect to water?

Answer 1

Answer:

Mass of empty density bottle = 30 gm

mass of density bottle with water in it 62 gm

Mass if density bottle with the liquid = 54 gm

Mass of water only = 62-30=32 gm

(a) Now volume of 1 g of water = 1cm

3

∴ Volume of density bottle = 32 cm

3

(b) Mass of liquid only = 54-30=24 gm

∴ density of the liquid = ∴

Volumeofliquid
