What is the definition of Volume?

• The amount of two-dimensional space that a substance occupies.

• The amount of three-dimensional space that a substance or object occupies, used as a primary way to quantify matter.

• The weight of a substance in a given space.

• The density of a substance in a specific volume.

What is a Conversion Factor?

• A method to calculate the area of a shape.

• A ratio derived from the equality between two different units that can be used to convert from one unit to another.

What is Molar Mass?

• The mass of one mole of a given chemical element or chemical compound, typically expressed in grams per mole (g/mol).

• The total weight of a substance regardless of its chemical composition.

• The weight of a single atom of an element measured in atomic mass units (amu).

What is an Atom?

• The smallest particle of a chemical element that retains its chemical properties and serves as the representative particle for elements.

• A large structure made up of multiple molecules.

• A type of chemical bond between two elements.

• A form of energy that can be released during a reaction.

What is a Representative Particle?

• A specific type of particle present in a substance, which can be an atom, a molecule, or a formula unit.

• A term used to describe the mass of a substance.

• A particle that is only found in gases.
