Question

What is the specific gravity of the metal, if the piece of metal weighs 150 grams in air and 125 grams in water?

Answer 1

Given: The piece of metal weighs 150 grams in air and 125 grams in water.

 

To find: The specific gravity of the metal.

Solution:

• Specific gravity, is the ratio of the density of a substance to the density of a given reference material.

• As we know that the formula for specific gravity is given by:

           weight of object / weight of same volume of water

• Also we know that buoyancy/ upthrust is an upward force that fluids exerts which opposes the weight of an immersed object.

• So, buoyancy is given by weight of displaced water

           = 150 – 125

           = 25 gm

• Therefore Specific gravity of metal will be

           = 150 / 25  

           = 6

Answer:

           The specific gravity of the metal is 6.

Answer 2

Answer:

125 grams in water

150 grams in piece of metal weights

specific gravity of metal=?

Step-by-step explanation:

The specific gravity of metal, it's known as the substances of water.

it gives subtracted

150-125=25gr

specific gravity of metal,

=150/25

=6 grams
