An object with 15 grams mass is immersed in benzene and suffers an apparent loss of mass 5g What is the approximate specific gravity of the object? (specific gravity of benzene = 0.7)

volume of object * .7 g/cm^3 = 5 g

so
V = 5/.7 = 7.14 cm^3

density = 15/7.14 = 2.1 g/cm^3
or specific gravity of 2.1 times water

To find the approximate specific gravity of the object, we need to understand the concept of specific gravity and how it is calculated.

Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance. In this case, we are comparing the density of the object to the density of benzene.

To calculate the specific gravity, we can use the following formula:

Specific Gravity = (Density of Object) / (Density of Reference Substance)

Now, let's analyze the given information:

Mass of the object = 15 grams
Loss of apparent mass when immersed in benzene = 5 grams
Specific gravity of benzene = 0.7

To find the density of the object, we need to calculate the actual mass of the object. The apparent loss of mass is due to the buoyant force acting on the object when it is immersed in a fluid. The buoyant force depends on the density of the fluid.

Actual mass of the object = Mass of the object - Loss of apparent mass

Plugging in the values:
Actual mass of the object = 15 grams - 5 grams = 10 grams

Now, we need to find the density of the object by dividing the actual mass of the object by its volume.

Density = Mass / Volume

Since we don't have the volume of the object, we cannot calculate its density precisely. However, we can still approximate the specific gravity by assuming the volume of the object remains constant after being immersed in benzene.

So, the specific gravity of the object can be calculated as follows:

Specific Gravity = (Density of Object) / (Density of Reference Substance)
= (Approximated Density of Object) / (Density of Benzene)

Since we assumed the volume remains constant:

Density of Object = Mass of the Object / Volume of the Object
= 10 grams / Volume of the Object

Finally, the approximate specific gravity can be calculated as:
Specific Gravity ≈ (10 grams / Volume of the Object) / (0.7)

Without further information about the volume of the object, we cannot provide an exact value for the specific gravity.

To find the specific gravity of the object, we can use the formula:

Specific Gravity = (mass of the object) / (mass loss in the liquid)

Given:
Mass of the object = 15 grams
Mass loss in the liquid = 5 grams

Plugging in the values, we get:

Specific Gravity = 15 / 5
Specific Gravity = 3

So, the approximate specific gravity of the object is 3.
