Question

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 (a) volume of bottle (b) density of liquid.​

Answer 1

$\huge\underline{\overline{\mid{\bold{\orange{Given-}}\mid}}}$

• 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

$\huge\underline{\overline{\mid{\bold{\purple{Solution-}}\mid}}}$

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
