A solid weight 4.8 I. air 2.8g in water and 3.2 in kerosene.
Calculate the ration of density of solid to that of the kerosene.
density of solid = 4.8/volume
density of kerosene= (4.8-3.2)/volume
ratio = 4.8/1.6=3
To calculate the ratio of the density of the solid to that of kerosene, we need to find the densities of both substances. Density is defined as mass divided by volume.
Given data:
- Weight of the solid in air = 4.8 g
- Weight of the solid in water = 2.8 g
- Weight of the solid in kerosene = 3.2 g
First, we need to determine the volume of the solid in each medium.
1. Volume of the solid in air:
Since the weight of the solid in air is given, we can assume that the density of air is negligible compared to the density of the solid. Therefore, the volume of the solid in air is the same as its volume in general.
2. Volume of the solid in water:
The weight of the solid in water indicates an apparent loss in weight due to the buoyant force acting on it. This buoyant force is equal to the weight of the water displaced by the solid. Using this information, we can calculate the volume of the solid in water.
To find the density ratio, we need to calculate the densities of the solid and kerosene:
Density of the solid = Mass of the solid / Volume of the solid in air
Density of the kerosene = Mass of the kerosene / Volume of the kerosene
Finally, we can find the ratio of the density of the solid to the density of kerosene by dividing the density of the solid by the density of kerosene.
Density ratio = Density of the solid / Density of kerosene
By performing the calculations with the given weights and using the principles of buoyancy for the volume in water, you can find the ratio of the density of the solid to that of the kerosene.
