Chemistry: Stochiometry

Avogadro’s number

6.02 × 10²³

stoichometry

determining the amount of reactant or product they require or will need for the reaction

What is a mole ratio?

compares the relative number of moles of two substances involved in a reaction.

Limiting Reagent

reactant that controls, or limits, the quantity of product that can be formed in that reaction

excess reagent

reactant that is not completely used up in the reaction

theoretical yield

expected amount of product formed during a chemical reaction if the limiting reagent completely reacts

actual yield

the amount of product actually formed in a chemical reaction

perecent yield

ration compared the actual yield of a product to its theoretical yield

Define molarity

The number of moles per 1 Liter of solution.

what does the concentration of a solution measure?

the amount of solute dissolved in a specific amount of solvent or solution.

Molarity

how the concentration of a solution is often expressed, the number of moles per

1 Liter of solution.

What is the formula for molarity?

amount of solute(moles)/volume of solution(liters)
