Buckminsterfullerene, or C60, is considered a simple molecular substance because it consists of discrete molecules made up of 60 carbon atoms arranged in a spherical shape, resembling a soccer ball. The carbon atoms are bonded together through strong covalent bonds, but the interactions between the C60 molecules are relatively weak van der Waals forces. This results in distinct molecular units that can exist independently, characteristic of simple molecular substances. Its relatively low melting point and volatility further emphasize its molecular nature.

Which substance shows a substance that is not molecular?
A formula unit.
What is a molecule a group of?
A Molecular Substance or Compound.
What are mol?
the molecular weight of a substance expressed in grams
How can you find the molecular mass of a substance from its mass spectrum?
Obtain the molecular mass by determining the m/z value of the molecular ion peak (rightmost in the spectrum).
How do you differentiate simple molecular compounds and giant molecular compounds?
Simple molecular compounds have discrete molecules held together by weak intermolecular forces, while giant molecular compounds have repeating units bonded together by strong covalent bonds. Simple molecular compounds typically have low melting and boiling points and are often gases or liquids at room temperature, while giant molecular compounds tend to have high melting and boiling points and are usually solids at room temperature.

What is a molecule a group of?
A Molecular Substance or Compound.
How is a molecular substance similar and different from molecular elements?
"Molecular element" is a much narrower category than "molecular substance". The kinetic units* of a molecular element contain at least two atoms, but all the atoms in the kinetic unit must be atoms of the same element. A molecular substance may contain any number of atoms of any number of elements. Therefore, every molecular element is a molecular substance, but the reverse is not true. The only additional requirements for a molecular substance are that all its kinetic units must have the same chemical composition and must contain at least two atoms but must not have any net electrical charge. ____________________________________________ *A kinetic unit is the smallest portion of a substance that moves further apart on average from other kinetic units when the substance expands while maintaining nearly constant interatomic distances within the kinetic unit itself.
Can one substance have same empirical and molecular formula?
Yes, it is possible for a substance to have the same empirical and molecular formula. This can occur when the substance is composed of only one type of element, such as oxygen gas (O2), where both the empirical and molecular formula are O2.
What is the significance of the molecular mass (symbol) in determining the properties of a substance?
The molecular mass (symbol) of a substance is significant in determining its properties because it affects how the substance interacts with other molecules. Substances with higher molecular masses tend to have different physical and chemical properties compared to substances with lower molecular masses. This is because the molecular mass influences factors such as boiling point, melting point, and solubility, which are important in understanding the behavior of a substance.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
