Question

Briefly describe how will you find experimental density of kerosene oil with a density bottle

Answer 1

"Here is what you need to do.

Find the mass of an empty density bottle.

After that, fill the bottle with water and weigh the bottle once again.

Now repeat the same with kerosene.

Now to find the mass of the water, you need to follow –

(weight of the bottle+ weight of the water)- (mass of the bottle)

Now to find the mass of the kerosene you need to do –

(weight of the bottle+ weight of the kerosene)- (mass of the bottle)

Now, divide the mass of the kerosene by mass of the water and you will get the density of kerosene.

"

Answer 2

Answer:

Wash the density bottle with distilled water and then dry it in a hot air.insert the stopper and find its mass on a physical balance.

i)find the density bottle with distilled water completely and then insert the glass stopper.wipe the bottle dry from outside and find its mass on a physical balance.

ii) pour off the water from the density bottle and dry it in hot air. fill the density bottle with the given liquid (say kerosine oil, alcohol,brine, solution etc. insert the stopper and wipe the bottle dry from outside. find the mass of density bottle and liquid on a physical balance.
