Chapter 6:Chemical Reactions: Mole and Mass Relationships

theoretical yield

The amount of product you obtain if the limiting reagent is completely consumed is called the ________ of the reaction.

One mole

________ of any substance is the amount having a mass in grams- its molar mass- numerically equal to its molecular or formula mass in amu.

STEP 1

Write the balanced chemical equation

STEP 2

Choose molar masses and mole ratios to convert the known information into the needed information

STEP 3

Set up the factor-label expressions

STEP 4

Calculate the answer and check the answer against the ballpark estimate you made before you began your calculations

molecular mass

average mass of the substance's molecules.

atomic mass

average mass of the substance's atoms.

limiting reagent

The reactant that is exhausted first in a reaction

percent yield

Percent yield = (Actual yield/ Theoretical yield) * 100
