Stoichiometry, Units Only

Front

What is stoichiometry?

Back

Stoichiometry is the branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the conservation of mass.

What is a mole ratio?

Back

A mole ratio is a conversion factor derived from the coefficients of a balanced chemical equation, used to relate the amounts of reactants and products.

Front

How do you calculate percent yield?

Back

Percent yield is calculated using the formula: Percent Yield = (Actual Yield / Theoretical Yield) x 100%.

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, based on stoichiometric calculations.

Front

What is the actual yield?

Back

The actual yield is the amount of product that is actually obtained from a chemical reaction, which is often less than the theoretical yield.

Front

What is the first step in stoichiometric calculations?

Back

The first step is to write a balanced chemical equation for the reaction.

Front

What is the significance of the coefficients in a balanced equation?

Back

The coefficients indicate the number of moles of each substance involved in the reaction and are used to determine mole ratios.

Front

What is a conversion factor in stoichiometry?

Back

A conversion factor is a ratio used to convert between different units or quantities, such as moles to grams.

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance by its molar mass: Moles = Mass (g) / Molar Mass (g/mol).

Front

What is the molar mass of a compound?

Back

The molar mass of a compound is the sum of the atomic masses of all the atoms in its formula, expressed in grams per mole (g/mol).
