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.

Text Solution

Verified by Experts

Mass of empty density bottle =20.25 g
Mass of empty density bottle +water =50.25
Mass of empty density bottle +liquid =40.75 g
`:.` Mass of only water = `1cm^(3)`
`:.` Volume of bottle = Volume of only water `=30cm^(3)`
Also, the mass of liquid only =(40.75-20.25)g=20.50g
`:.` Density of liquid `=(M)/(V)=(20.50g)/(30cm^(3))=0.683g//cm^(3)`
