• volumes and pressures

• temperatures and heat

• concentrations and solubility

Molar volume is defined as:

• The volume occupied by one mole of a substance

• The mass of one mole of a substance

• The density of a substance

• The temperature at which a substance boils

The definition of Mole ratio is:

• The ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

• The ratio of the mass of one substance to the mass of another substance.

• The ratio of the volume of one gas to the volume of another gas under the same conditions.

• The ratio of the number of atoms of one element to the number of atoms of another element in a compound.

The definition of Mass-mass problem is:

• A problem involving the conversion of mass from one substance to another using stoichiometry.

• A problem related to the measurement of mass in physics.

The definition of Limiting reagent (reactant) is:

• The reactant that is completely consumed in a reaction, limiting the amount of product formed.

• The reactant that is in excess and remains after the reaction is complete.

• The reactant that speeds up the reaction without being consumed.

• The reactant that is used to balance the chemical equation.

Excess reagent (reactant) is defined as:

• The reactant that is completely consumed in a reaction.

• The reactant that remains after a reaction has completed.

• The reactant that determines the amount of product formed.

• The reactant that is used in the smallest amount.

Theoretical yield is defined as:

• The amount of product that can be produced in a reaction under ideal conditions.

• The actual amount of product obtained from a reaction.

• The amount of reactants used in a chemical reaction.

• The efficiency of a chemical reaction.

The definition of Molar mass is:

• The mass of one mole of a substance, usually expressed in grams per mole.

• The volume of one mole of a substance, usually expressed in liters per mole.

• The density of a substance, usually expressed in grams per cubic centimeter.

• The concentration of a solution, usually expressed in moles per liter.

The definition of Mole is:

• A small burrowing mammal

• A unit of measurement in chemistry

• A type of skin lesion
