Question

11. The mass of an empty density bottle is 45 g. When it is filled with water, it weighs 90 g and 80 g when it filled completely with an unknown liquid. Find:
a) Volume of density bottle
b) Density of liquid
c) Relative density of liquid​

Answer 1

Answer:

Mass of empty density bottle, M1 = 30 grams

MAss of bottle and water, M2 = 75 grams

Mass of liquid and liquid x, M3 = 65 grams

Mass of water = M2 – M1 = 45 grams...

a) Volume :-

Volume of density bottle = Mass of water = 45 grams..

b) Density :-

• Density of liquid x, D = mass of liquid/mass of water = 35/45

• Mass of iquid = M3 – M1 = 65 – 30 = 35 grams

• D = Mass of liquid/mass of water = 35/45 = 0.77 grams/cm3..

c) Relative density :-

• Mass of water in the density bottle = 75 – 30 = 45 grams

• Therefore, the volume of water in density bottle = 45 cc

• Mass of the liquid whose volume is equal to the density bottle = 65 – 30 = 35 grams

Therefore, relative density of the liquid = mass of 45 cc of liquid/mass of 45 cc of water = 35/45 = 7/9 = 0.77...
