1.	An empty density bottle is 20 g, when filled with water is 30g, when filled with a dense liquid is 60g. Find RD of liquid.
Answer» 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 of density bottle = Mass of water = 45 grams b) 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) 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 Explanation:

An empty density bottle is 20 g, when filled with water is 30g, when filled with a dense liquid is 60g. Find RD of liquid.

Answer»

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 of density bottle = Mass of water = 45 grams

b) 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) 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
