Question

the mass of empty density bottle is 20 grams when filled completely with water it weighs 65 grams and 75 gram when filled completely with the liquid find the relative density of liquid .​​

Answer 1

HEY

HERE IS YOUR ANSWER

============================

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

HOLA MATE

ANSWER:-

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

also density is directly proportional to mass

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
