A piece of metal has a mass of 200 g and a volume of 40 cm3.
What is its specific gravity?
What is its density? g/cm3
To calculate specific gravity and density, we need to know the definition and formulas for these terms.
Specific gravity is the ratio of the density of a substance to the density of a reference substance. It is a unitless quantity.
Density, on the other hand, is defined as the mass of a substance divided by its volume. It is usually measured in grams per cubic centimeter (g/cm3).
To find the specific gravity, we divide the density of the substance by the density of the reference substance. In this case, we can use water as the reference substance, which has a density of 1 g/cm3 at standard conditions.
Now, let's find the specific gravity and density of the given piece of metal step by step:
Step 1: Calculate the density of the metal.
Density = mass / volume
Given:
Mass = 200 g
Volume = 40 cm3
Density = 200 g / 40 cm3
Density = 5 g/cm3
So, the density of the metal is 5 g/cm3.
Step 2: Calculate the specific gravity.
Specific Gravity = Density of the metal / Density of water
Given:
Density of water = 1 g/cm3
Specific Gravity = 5 g/cm3 / 1 g/cm3
Specific Gravity = 5
Therefore, the specific gravity of the given piece of metal is 5, and its density is 5 g/cm3.
