Question

An empty density bottle of Volume 50cc weigh 100g when completely filled With liquid of relative density 1.4 the mass of relative density bottle is what

Answer 1

Explanation:

Mass of empty R.D bottle = 26.4 gm

Mass of R.D bottle + water = 38.4 gm

Mass of R.D bottle + liquid = 35.4 gm

mass of only water = 38.4 -26.4 = 12 gm

Volume of 1 g of water = 1 cm

3

∴ Volume of 12 g of water = 12cm

3

Mass of only liquid = 35.4 - 26.4 = 9 gm

Volume of the liquid = 12cm

3

∴ Density of liquid =
