Mercury has a density of 13.6 g/cm^3. What is the specific gravity of mercury?
A. 13.6 g
B. 13.6 cm
C. 13.6 cm^3
D. 13.6
D
specific gravity is just a number; no units
It's the ratio of densities -- Hg:H2O
think its 13.6 g
To calculate the specific gravity of a substance, you need to compare its density to the density of water. The specific gravity of a substance is defined as the ratio of its density to the density of water.
Given that the density of mercury is 13.6 g/cm^3, you need to divide this by the density of water, which is approximately 1 g/cm^3.
So, the specific gravity of mercury is:
13.6 g/cm^3 / 1 g/cm^3 = 13.6
Therefore, the specific gravity of mercury is D. 13.6.
To determine the specific gravity of a substance, you need to compare its density to the density of water. The specific gravity is the ratio of the density of the substance to the density of water.
In this case, the density of mercury is given as 13.6 g/cm^3. The density of water is approximately 1 g/cm^3.
To find the specific gravity of mercury, divide its density by the density of water:
Specific Gravity = Density of Mercury / Density of Water
Specific Gravity = 13.6 g/cm^3 / 1 g/cm^3
So the specific gravity of mercury is 13.6.
Therefore, the answer is D. 13.6.
