Answer 1

Answer:

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

I hope you understand please mark my answer a brainliest answer

Answer 2

Hi friend ✌✌

Answer:

1) Density of glycerine is 2.666 g/cm^3 .

2) Density of iron is 160 g/cm^3 .

Density = Mass /Volume

Hope it helps you :--)
