Density is the measure of mass per unit volume of a substance. Mercury is a transition metal element and is the only metal which is liquid at room temperature. Mercury has density of density of 13.6 at 20°C
The density of mercury is 13.6 .
We know 1 gram per cubic centimeter () = 1,000 kilograms per cubic meter ()
Converting this into we get 13600
Mercury is a very dense and heavy metal. It is the only liquid that exists at room temperature. The density of mercury is 13.5 g/mL which is 13.5 times denser than water, this is why a small amount of mercury feels heavy.
Mercury is a toxic element and only metal that exists in liquid form. Touching mercury and washing hands instantly might not cause any problem. However, leaving it long on skin or if there are any minor cuts on skin then mercury can cause skin burns. Mercury is neurotoxic and affects the central nervous system when it enters the body.
