Question

. A density bottle of mass 100 g weighs 200 g when full of water. What would it weigh when full of mercury of relative density 13.6?
​

Answer 1

Answer:

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 cm3 

∴ Volume of 12 g of water = 12cm3

Mass of only liquid = 35.4 - 26.4 = 9 gm

Volume of the liquid = 12cm3

∴ Density of liquid = Vol.ofliquidMassofliquid=12cm39g=0.75g/cm3

R.D of the liquid = DensityofwaterDensityofliquid=1.00g/cm30.75g/cm3=0.75
