Stoichiometry: Gram to Gram

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.

Front

What must be true about a chemical equation before performing stoichiometric calculations?

Back

The chemical equation must be balanced.

Front

What is the purpose of conversion factors in stoichiometry?

Back

Conversion factors are used to convert between different units, such as grams and moles, to facilitate calculations.

Front

What is the molar mass of a substance?

Back

The molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

How do you determine the molar mass of a compound?

Back

To determine the molar mass, sum the atomic masses of all the atoms in the compound's formula.

Front

What goes in the upper left and bottom right of conversion factors in stoichiometry?

Back

1 mole goes in the upper left and the corresponding unit in the bottom right.

Front

What is the relationship between moles and grams in stoichiometry?

Back

Moles can be converted to grams using the molar mass of the substance.

Front

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

Back

Coefficients indicate the relative number of moles of each substance involved in the reaction.

Front

What is the first step in a stoichiometric calculation?

Back

The first step is to ensure that the chemical equation is balanced.

Front

What is the last step in a stoichiometric calculation?

Back

The last step is to cancel out units, then multiply top times top, bottom times bottom, and divide.
