Unit 7 Vocabulary - Mole and Stoichiometry

Front

What is Stoichiometry?

Back

Stoichiometry is the calculation of quantities in chemical reactions, based on the relationships between reactants and products in a balanced chemical equation.

Front

What is Dimensional Analysis?

Back

Dimensional analysis is a method to analyze and solve problems using the units, or dimensions, of the measurements.

Front

What is an Empirical Formula?

Back

An empirical formula is the formula that shows the lowest whole-number ratio of elements in a compound, with subscripts reduced to their simplest form.

Front

What is a Mole Ratio?

Back

A mole ratio is the ratio between the numbers of moles of any two substances in a balanced chemical equation, derived from the coefficients in the balanced equation.

Front

What is Molar Mass?

Back

Molar mass is the mass in grams of 1 mole of a substance, typically expressed in g/mol.

Front

What is Actual Yield?

Back

Actual yield is the amount of product that is actually obtained from a chemical reaction, as opposed to the theoretical yield.

Front

What is Theoretical Yield?

Back

Theoretical yield is the maximum amount of product that could be formed from given amounts of reactants, based on stoichiometric calculations.

Front

What is Percent Yield?

Back

Percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage.

Front

What is Molar Volume?

Back

Molar volume is the volume occupied by one mole of a substance, typically measured at standard temperature and pressure (STP), which is 22.4 L for gases.

Front

What is Avogadro's Number?

Back

Avogadro's number is 6.022 x 10^23, which is the number of particles (atoms, molecules, etc.) in one mole of a substance.
