Mass of density bottle is 40 g when empty, 60 g when filled with water

1.	Mass of density bottle is 40 g when empty, 60 g when filled with water, 53 g when filled with alcohol. Find the volume of density bottle & relative density of alcohol.
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:

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
