A density bottle weighs 20.25 g when empty , 40.75 g when filled with a liquid and 50.25 g when filled with water. Find the volume of bottle and density of liquid.
Answers
Answer:
Mass of empty density bottle = 30 gm
mass of density bottle with water in it 62 gm
Mass if density bottle with the liquid = 54 gm
Mass of water only = 62-30=32 gm
(a) Now volume of 1 g of water = 1cm3
∴ Volume of density bottle = 32 cm3
(b) Mass of liquid only = 54-30=24 gm
∴ density of the liquid = ∴Volume of liquid Mass of liquid only
=32cm324g=0.75g/cm3
Answer
initial mass of bottle is 20.25 g
the 50.25 g when it is filled with water
mass of bottle when it is filled with liquid is 40.75
mass of water =50.25-20.25
= 30 g
Density = 1000 g/ltr
from density formula we will find the volume so the volume = 0.03 ltr or 30 ml
mass of liquid =40.75-20.25=20.50g
density of liquid= mass of liquid/ volume of water
= 20.50/0.03
= 682.33 gm/l
