If you understand what molecular weight (MW or FW) means, then look at the molecular weight of one molecule of Mercury (Hg2) and compare that to the molecular weight of an H2O molecule.

Which is heavier?

Why mercury weigh more than water?

13.7 times more. Because the atoms of mercury are heavier (more massive) than the molecules of water AND they're closer together.


Why doesn't 10mL of mercury have the same density a 10mL of water?

Mercury and water have different densities due to their molecular structures. Mercury is much denser than water because the mercury atoms are more tightly packed compared to water molecules, which makes mercury heavier for the same volume. This difference results in mercury having a higher density compared to water.


Why a molecule is bigger than a atom?

Answer 1: Because a molecule is made up of atoms. Correct answer: it's a trick or meaningless question. Molecules are not always larger or heavier than atoms. For example, a single uranium atom is larger and heavier than a hydrogen molecule (H2) or even a water molecule (H2O).

How many water molecules are formed if a glycerol molecule is combined with three fatty acid molecules?

Three water molecules are formed when a glycerol molecule combines with three fatty acid molecules in a condensation reaction. Each fatty acid molecule contributes a water molecule when it reacts with the glycerol molecule to form a triglyceride.


What liquid is less viscous yet heavier than water?

Mercury is a liquid that is less viscous but heavier than water. Mercury is a dense liquid metal at room temperature, making it heavier than water, which is less viscous than water due to its lower viscosity.
