Question

An empty RD bottle weighs 60 g but weighs 120 g when completely filled with water. When the bottle is completely filled with an unknown liquid it weighs 90 g .Calculate the :
a)volume of the RD bottle
b)density of the unkown liquid​

Answer 1

Step-by-step explanation:

a) Pls Find it attached below

b) 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
