Question

An empty RD bottle weighs 60g but weighs 120g when completely filled with water. When the bottle is completely filled with an known liquid,.it weighs 90g. Calculate the volume of the RD bottle and density of the unknown liquid.

Answer 1

As the unknown liquid will occupy the same volume as water does but possess less mass as compared to water
For water density can be taken as 1
Then the volume is 60 ml.
Now the density 60/60 comes 1 which we have thought
But for unknown liquid it has 30 g mass
Then 30/60 accounts for 0.5 and hence it will be less dense as compare to water .. Half the value of density of water

Answer 2

Answer:

Explanation:

As the unknown liquid will occupy the same volume as water does but possess less mass as compared to water

For water density can be taken as 1

Then the volume is 60 ml.

Now the density 60/60 comes 1 which we have thought

But for unknown liquid it has 30 g mass

Then 30/60 accounts for 0.5 and hence it will be less dense as compare to water .. Half the value of density of water
