Question

The mass of empty density bottle is 20 gram, when filled completely with water it weighs 65 gram and 75 garm when filled completely with a liquid. Find the relative density of liquid​

Answer 1

Explanation:

Relative density=density of liquid(d1)/density of water at 4℃(d2)

also density is directly proportional to mass

therfore d1/d2=m1/m2

now m1=35

and m2=mass of liquid-mass of empty bottle=45

relative density=35/45=0.77

now

0.77=density of liquid/density of water

density of liquid=0.77*1

density of liquid=0.77g/cm^3

density=mass/volume

volume=35/0.77

volume=45cm^3
