Question

A piece of metal has a mass of 200g and a volume of 2cm^3. What is it’s specific gravity?

Answer 1

Answer:

specific gravity = 100

Explanation:

Data Given:

mass of the metal = 200 g

volume = 2 cm³

specific gravity = ?

Solution:

Specific gravity:

It is the measure of the relative density i.e density of the metal divided by the density of the water

Formula Used:

      S.G = density of the substance / density of water at 4°C . . . . . . (1)

As we know

density of water at 4°C = 1 g/cm³

So first we have to find density of metal

formula will be used to calculate density

           d = m/v

put values in above formula

         d = 200 g/ 2 cm³

         d = 100 g/cm³

Now put values in equation 1

              S.G = density of the substance / density of water at 4°C

              S.G = 100 g/cm³ / 1 g/cm³

              S.G = 100

So, the specific gravity of the metal = 100
