Question

The weight of an object is 200 g.When it is emerged in water its weight becomes 100g. When it is emerged in another liquid it's weight becomes 150g. Find the relative density of that object.

Answer 1

the relative density of that object is 1.25

Answer 2

Answer:

If an object has a weight of 100 gm in air and 80 gm in water, what will be the density of the object?

First, calculate the loss in mass = 100 g - 80 g = 20 g h2o displaced

The density of water = 1 g / mL

So, the object displaced 20 mL of water, which equals the volume of the object.

With that, we can calculate the relative density when kept in water, which equals -> mass / volume

The object’s relative density = 80 g / 20 mL

Then the relative density = 4 g / mL

If an object has a relative density greater than the liquid you’re putting it in, then it will sink. In this case, the relative density of the object is 4g / mL, which is greater than the 1 g / mL for water. So, the object would sink.
