Question

5. An empty density bottle weighs 25 g. When completely filled with water, it weighs 55 g and
when completely filled with a liquid, it weighs 52 g. Calculate i. volume of the density bottle
and ii. density of the liquid.
[Ans: i. 30 cm ii. 0.9 g/cm]​

Answer 1

Explanation:

Mass of empty density bottle= 25g

Mass of bottle filled with water = 55g

Mass of water = 55-25g

=30g

Volume of water = 1g/cm³

Now, Density=Mass/volume

1g/cm³=30g/vol

vol of density bottle = 30cm³

Mass of bottle filled with liquid= 52g

Mass of fluid =52-25g

=27g

Density of liquid=27/30

=0•9g/cm³
