A solid has a mass of 200g in air and when partly immersed in a certain liquid it has a mass of 160g.Given that the relative density of the liquid is 0.80 calculate the volume of the solid immersed in the liquid

is there any answers you can write down?

like the answer A
and answer B
etc
or is this a writing problem?

To find the volume of the solid immersed in the liquid, we need to use the concept of relative density. Relative density is the ratio of the density of a substance to the density of another substance, usually water.

In this case, the relative density of the liquid is given as 0.80. This means that the density of the liquid is 0.80 times the density of water.

First, we need to find the density of the solid. Since we are given the mass of the solid in air, we can assume that the density of air is negligible compared to the solid and the liquid.

The mass of the solid in air is 200g, and when it is partly immersed in the liquid, its mass becomes 160g. This means that the loss in mass is due to the liquid displacing some of the solid's volume.

The loss in mass is 200g - 160g = 40g. This is the mass of the liquid displaced by the solid.

Next, we need to find the density of the solid. Density is defined as mass divided by volume. Therefore, the density of the solid can be calculated as:

Density of solid = Mass of solid / Volume of solid

Let's assume the volume of the solid immersed in the liquid is V liters.

Now, we can use the concept of relative density. The relative density of the liquid is given as 0.80, which means the density of the liquid is 0.80 times the density of water. The density of water is approximately 1000 kg/m³.

Density of liquid = Relative density of liquid × Density of water
Density of liquid = 0.80 × 1000 kg/m³ = 800 kg/m³

Now, we have the density of the liquid and the mass of the liquid displaced by the solid. We can use these values to find the volume of the solid immersed in the liquid.

Density of liquid = Mass of liquid / Volume of liquid
800 kg/m³ = 40g / V

Since the units for density are in kg/m³, we need to convert the mass of the liquid to kg. 40g = 0.04kg.

800 kg/m³ = 0.04kg / V

V = (0.04kg) / (800 kg/m³)
V = 0.00005 m³

So, the volume of the solid immersed in the liquid is 0.00005 m³.
